You have now finished your do-it-yourself CNC router, or you went out and bought one. You have been waiting a long time for this and now it has last but not least happened. But by now your girlfriend is jealous simply because you really don’t invest enough time with her, or worse your spouse is pissed off about all the money you have spent on this funky looking contraption. You feel to oneself I’ll show her, I’ll go out to the shop or the basement and I’ll make a thingumabob that will genuinely impress her. But first you examine the world wide web to see how the big boys do it, just to discover a small handful of cheesy g code files that are compatible with your CNC router software. Even after weeks and weeks of browsing you cannot locate something that will impress your lady or your neighbors, now what ?
Let me tell you that your not by yourself. Ive been in the business for much more than fifteen decades and I have heard it all. In this post I will reveal all the ins and outs that the huge boys use. All their suggestions and tricks that they wont tell you.
Overlook the G code. This is just a waste of time. In this day and age you want to think like the huge boys do. Your stop file WILL be g code, nevertheless you really don’t want to know nearly anything about it. The massive boys will have a 3D modeler layout and draw the 3d image, once its drawn they will convert this to a file sort like .STL then load that into a CAM plan that can generate g code for the kind of CNC router application they use. I know this seems complicating, but I will present you a few shortcuts.
Except if you want a Really distinct 3D picture you wont require to draw significantly of something. There are websites that you can acquire the 3D Reliefs (3D Photographs for CNC routers) The one particular I like the most is www.3DReliefs.com basically since they have a wonderful assortment at quite sensible charges.
Your router spindle motor collet, needs to be ready to accept Dremel bits. I can’t tension adequate on this. I don’t treatment how you do it, just do it. Except you are producing large signs or pieces you will will need to use Dremel bits. This is due to the fact the smaller sized the piece, the smaller the cavities will be, and unless you have tremendous little bits, all individuals tiny facts wont display. Dremel bits are cheap, tried using and accurate replacements for these extremely expensive bits that the huge boys use.
The CNC router handle program that I propose is Mach3 CNC. The CAD/CAM software program that I propose is Artcam. This is a remarkable piece of computer software that you can’t do without having. They have a trial version that I suggest waiting up to the very very last minute to download, this way you will be ready to use it, instead of just having it on your Pc desktop staring at you even though the trial period of time expires. This method will be ready to export the G code to your CNC router system. But don’t be fooled, It will do a thousand issues far more then just that.
Lets seem into Artcam a bit a lot more here. You initial Acquire a 3D Relief from www.3DReliefs.com then you will load and scale this into artcam, then you will decide on device paths, and in device paths you will need to produce three to 4 instrument paths with different size bits. Your initial bit will much more than probable be 1/two inch to 3/eight inch ball nose based on the size of the model you will be producing. then down to one/four inch ball nose, then down to 1/eight inch ball nose then down to about a 106 Dremel bit. You will need to configure each and every bit in the device bit database. The phase over percentage is instead challenging, I have identified that all around 9% is my sweet spot. its a bit slow, but I don’t have to sand so a lot, but I conserve this modest step more than for just the Dremel bit, the other individuals can be all around forty%. And except your router and bits are like superman you will a lot more than probably have a feed price of around one hundred inches per minute. significantly less than 40 will burn off up your bits. more than 200 will begin to chip up wood and cause cavities. With much more pricey bits, the more quickly you can go, but we wont get into that in this post. If you have a variable velocity spindle motor or router then you will be ready to management the speed to help save your bits from burning up. In Artcam you can set the spindle pace for each bit. Artcam can get a bit tough and confusing. I’m sorry but I can’t get into each and every minor detail in this article. Artcam is just to complicated to go over every thing, so lets retain it straightforward.
So now we have three or 4 instrument paths. dependent on your CNC router you may well be capable to produce one big G code with all three or four bits in it. But lets keep it basic and create 3 or 4 G codes with the identify of the bits. So you will pick the instrument route and decide on your G code CNC requirement file format and for illustration save as “fifty percent inch ball nose.cnc” in a directory with the name of the piece you will be generating, since there will be many instrument paths within of this directory.
When you have all the device paths saved into your directory you will duplicate this dir into your CNC router controller Personal computer. and load the initial G code file into your CNC router plan. A single by 1 until you have completed the dremel bit.
Summary:
Overlook understanding G code
Router spindle motor collet, requirements to be capable to accept Dremel bits.
You can buy the 3D Reliefs from www.3DReliefs.com
The CNC router manage method that I recommend is Mach3 CNC.
The CAD/CAM computer software that I recommend is Artcam.
9% is my sweet spot for the dremel bit stage more than in the bits database.
Feed fee of about 100 inches per moment.
Generate 3 to 4 tool paths with distinct size bits.
Then Lower N Go………..

Network Routing Protocols – IGRP, EIGRP, OSPF, ISIS, BGP
011 months ago

Overview
The purpose of routing protocols is to learn of available routes that exist on the enterprise network, build routing tables and make routing decisions. Some of the most common routing protocols include RIP, IGRP, EIGRP, OSPF, IS-IS and BGP. There are two primary routing protocol types although many different routing protocols defined with those two types. Link state and distance vector protocols comprise the primary types. Distance vector protocols advertise their routing table to all directly connected neighbors at regular frequent intervals using a lot of bandwidth and are slow to converge. When a route becomes unavailable, all router tables must be updated with that new information. The problem is with each router having to advertise that new information to its neighbors, it takes a long time for all routers to have a current accurate view of the network. Distance vector protocols use fixed length subnet masks which aren’t scalable. Link state protocols advertise routing updates only when they occur which uses bandwidth more effectively. Routers don’t advertise the routing table which makes convergence faster. The routing protocol will flood the network with link state advertisements to all neighbor routers per area in an attempt to converge the network with new route information. The incremental change is all that is advertised to all routers as a multicast LSA update. They use variable length subnet masks, which are scalable and use addressing more efficiently.
Interior Gateway Routing Protocol (IGRP)
Interior Gateway Routing Protocol is a distance vector routing protocol developed by Cisco systems for routing multiple protocols across small and medium sized Cisco networks. It is proprietary which requires that you use Cisco routers. This contrasts with IP RIP and IPX RIP, which are designed for multi-vendor networks. IGRP will route IP, IPX, Decnet and AppleTalk which makes it very versatile for clients running many different protocols. It is somewhat more scalable than RIP since it supports a hop count of 100, only advertises every 90 seconds and uses a composite of five different metrics to select a best path destination. Note that since IGRP advertises less frequently, it uses less bandwidth than RIP but converges much slower since it is 90 seconds before IGRP routers are aware of network topology changes. IGRP does recognize assignment of different autonomous systems and automatically summarizes at network class boundaries. As well there is the option to load balance traffic across equal or unequal metric cost paths.
Characteristics
· Distance Vector
· Routes IP, IPX, Decnet, Appletalk
· Routing Table Advertisements Every 90 Seconds
· Metric: Bandwidth, Delay, Reliability, Load, MTU Size
· Hop Count: 100
· Fixed Length Subnet Masks
· Summarization on Network Class Address
· Load Balancing Across 6 Equal or Unequal Cost Paths ( IOS 11.0 )
· Metric Calculation = destination path minimum BW * Delay (usec)
· Split Horizon
· Timers: Invalid Timer (270 sec), Flush Timer (630 sec), Holddown Timer (280 sec)
Enhanced Interior Gateway Routing Protocol (EIGRP)
Enhanced Interior Gateway Routing Protocol is a hybrid routing protocol developed by Cisco systems for routing many protocols across an enterprise Cisco network. It has characteristics of both distance vector routing protocols and link state routing protocols. It is proprietary which requires that you use Cisco routers. EIGRP will route the same protocols that IGRP routes (IP, IPX, Decnet and Appletalk) and use the same composite metrics as IGRP to select a best path destination. As well there is the option to load balance traffic across equal or unequal metric cost paths. Summarization is automatic at a network class address however it can be configured to summarize at subnet boundaries as well. Redistribution between IGRP and EIGRP is automatic as well. There is support for a hop count of 255 and variable length subnet masks.
Convergence
Convergence with EIGRP is faster since it uses an algorithm called dual update algorithm or DUAL, which is run when a router detects that a particular route is unavailable. The router queries its neighbors looking for a feasible successor. That is defined as a neighbor with a least cost route to a particular destination that doesn’t cause any routing loops. EIGRP will update its routing table with the new route and the associated metric. Route changes are advertised only to affected routers when changes occur. That utilizes bandwidth more efficiently than distance vector routing protocols.
Autonomous Systems
EIGRP does recognize assignment of different autonomous systems which are processes running under the same administrative routing domain. Assigning different autonomous system numbers isn’t for defining a backbone such as with OSPF. With IGRP and EIGRP it is used to change route redistribution, filtering and summarization points.
Characteristics
· Advanced Distance Vector
· Routes IP, IPX, Decnet, Appletalk
· Routing Advertisements: Partial When Route Changes Occur
· Metrics: Bandwidth, Delay, Reliability, Load, MTU Size
· Hop Count: 255
· Variable Length Subnet Masks
· Summarization on Network Class Address or Subnet Boundary
· Load Balancing Across 6 Equal or Unequal Cost Paths (IOS 11.0)
· Timers: Active Time (180 sec)
· Metric Calculation = destination path minimum BW * Delay (msec) * 256
· Split Horizon
· LSA Multicast Address: 224.0.0.10
Open Shortest Path First (OSPF)
Open Shortest Path First is a true link state protocol developed as an open standard for routing IP across large multi-vendor networks. A link state protocol will send link state advertisements to all connected neighbors of the same area to communicate route information. Each OSPF enabled router, when started, will send hello packets to all directly connected OSPF routers. The hello packets contain information such as router timers, router ID and subnet mask. If the routers agree on the information they become OSPF neighbors. Once routers become neighbors they establish adjacencies by exchanging link state databases. Routers on point-to-point and point-to-multipoint links (as specified with the OSPF interface type setting) automatically establish adjacencies. Routers with OSPF interfaces configured as broadcast (Ethernet) and NBMA (Frame Relay) will use a designated router that establishes those adjacencies.
Areas
OSPF uses a hierarchy with assigned areas that connect to a core backbone of routers. Each area is defined by one or more routers that have established adjacencies. OSPF has defined backbone area 0, stub areas, not-so-stubby areas and totally stubby areas. Area 0 is built with a group of routers connected at a designated office or by WAN links across several offices. It is preferable to have all area 0 routers connected with a full mesh using an Ethernet segment at a core office. This provides for high performance and prevents partitioning of the area should a router connection fail. Area 0 is a transit area for all traffic from attached areas. Any inter-area traffic must route through area 0 first. Stub areas use a default route to forward traffic destined for an external network such as EIGRP since the area border router doesn’t send or receive any external routes. Inter-area and intra-area routing is as usual. Totally stubby areas are a Cisco specification that uses a default route for inter-area and external destinations. The ABR doesn’t send or receive external or inter-area LSA’s. The not-so-stubby area ABR will advertise external routes with type 7 LSA. External routes aren’t received at that area type. Inter-area and intra-area routing is as usual. OSPF defines internal routers, backbone routers, area border routers (ABR) and autonomous system boundary routers (ASBR). Internal routers are specific to one area. Area border routers have interfaces that are assigned to more than one area such as area 0 and area 10. An autonomous system boundary router has interfaces assigned to OSPF and a different routing protocol such as EIGRP or BGP. A virtual link is utilized when an area doesn’t have a direct connection to area 0. A virtual link is established between an area border router for an area that isn’t connected to area 0, and an area border router for an area that is connected to area 0. Area design involves considering geographical location of offices and traffic flows across the enterprise. It is important to be able to summarize addresses for many offices per area and minimize broadcast traffic.
Convergence
Fast convergence is accomplished with the SPF (Dijkstra) algorithm which determines a shortest path from source to destination. The routing table is built from running SPF which determines all routes from neighbor routers. Since each OSPF router has a copy of the topology database and routing table for its particular area, any route changes are detected faster than with distance vector protocols and alternate routes are determined.
Designated Router
Broadcast networks such as Ethernet and Non-Broadcast Multi Access networks such as Frame Relay have a designated router (DR) and a backup designated router (BDR) that are elected. Designated routers establish adjacencies with all routers on that network segment. This is to reduce broadcasts from all routers sending regular hello packets to its neighbors. The DR sends multicast packets to all routers that it has established adjacencies with. If the DR fails, it is the BDR that sends multicasts to specific routers. Each router is assigned a router ID, which is the highest assigned IP address on a working interface. OSPF uses the router ID (RID) for all routing processes.
Characteristics
· Link State
· Routes IP
· Routing Advertisements: Partial When Route Changes Occur
· Metric: Composite Cost of each router to Destination (100,000,000/interface speed)
· Hop Count: None (Limited by Network)
· Variable Length Subnet Masks
· Summarization on Network Class Address or Subnet Boundary
· Load Balancing Across 4 Equal Cost Paths
· Router Types: Internal, Backbone, ABR, ASBR
· Area Types: Backbone, Stubby, Not-So-Stubby, Totally Stubby
· LSA Types: Intra-area (1,2) Inter-area (3,4), External (5,7)
· Timers: Hello Interval and Dead Interval (different for network types)
· LSA Multicast Address: 224.0.0.5 and 224.0.0.6 (DR/BDR) Don’t Filter !
· Interface Types: Point to Point, Broadcast, Non-Broadcast, Point to Multipoint, Loopback
Integrated IS-IS
Integrated Intermediate System – Intermediate System routing protocol is a link state protocol similar to OSPF that is used with large enterprise and ISP customers. An intermediate system is a router and IS-IS is the routing protocol that routes packets between intermediate systems. IS-IS utilizes a link state database and runs the SPF Dijkstra algorithm to select shortest paths routes. Neighbor routers on point to point and point to multipoint links establish adjacencies by sending hello packets and exchanging link state databases. IS-IS routers on broadcast and NBMA networks select a designated router that establishes adjacencies with all neighbor routers on that network. The designated router and each neighbor router will establish an adjacency with all neighbor routers by multicasting link state advertisements to the network itself. That is different from OSPF, which establishes adjacencies between the DR and each neighbor router only. IS-IS uses a hierarchical area structure with level 1 and level 2 router types. Level 1 routers are similar to OSPF intra-area routers, which have no direct connections outside of its area. Level 2 routers comprise the backbone area which connects different areas similar to OSPF area 0. With IS-IS a router can be an L1/L2 router which is like an OSPF area border router (ABR) which has connections with its area and the backbone area. The difference with IS-IS is that the links between routers comprise the area borders and not the router. Each IS-IS router must have an assigned address that is unique for that routing domain. An address format is used which is comprised of an area ID and a system ID. The area ID is the assigned area number and the system ID is a MAC address from one of the router interfaces. There is support for variable length subnet masks, which is standard with all link state protocols. Note that IS-IS assigns the routing process to an interface instead of a network.
Characteristics
· Link State
· Routes IP, CLNS
· Routing Advertisements: Partial When Routing Changes Occur
· Metric: Variable Cost (default cost 10 assigned to each interface)
· Hop Count: None (limited by network)
· Variable Length Subnet Masks
· Summarization on Network Class Address or Subnet Boundary
· Load Balancing Across 6 Equal Cost Paths
· Timers: Hello Interval, Hello Multiplier
· Area Types: Hierarchical Topology similar to OSPF
· Router Types: Level 1 and Level 2
· LSP Types: Internal L1 and L2, External L2
· Designated Router Election , No BDR
Border Gateway Protocol (BGP)
Border Gateway Protocol is an exterior gateway protocol, which is different from the interior gateway protocols discussed so far. The distinction is important since the term autonomous system is used somewhat differently with protocols such as EIGRP than it is with BGP. Exterior gateway protocols such as BGP route between autonomous systems, which are assigned a particular AS number. AS numbers can be assigned to an office with one or several BGP routers. The BGP routing table is comprised of destination IP addresses, an associated AS-Path to reach that destination and a next hop router address. The AS-Path is a collection of AS numbers that represent each office involved with routing packets. Contrast that with EIGRP, which uses autonomous systems as well. The difference is their autonomous systems refer to a logical grouping of routers within the same administrative system. An EIGRP network can configure many autonomous systems. They are all managed by the company for defining route summarization, redistribution and filtering. BGP is utilized a lot by Internet Service Providers (ISP) and large enterprise companies that have dual homed internet connections with single or dual routers homed to the same or different Internet Service Providers. BGP will route packets across an ISP network, which is a separate routing domain that is managed by them. The ISP has its own assigned AS number, which is assigned by InterNIC. New customers can either request an AS assignment for their office from the ISP or InterNIC. A unique AS number assignment is required for customers when they connect using BGP. There are 10 defined attributes that have a particular order or sequence, which BGP utilizes as metrics to determine the best path to a destination. Companies with only one circuit connection to an ISP will implement a default route at their router, which forwards any packets that are destined for an external network. BGP routers will redistribute routing information (peering) with all IGP routers on the network (EIGRP, RIP, OSPF etc) which involve exchange of full routing tables. Once that is finished, incremental updates are sent with topology changes. Each BGP router can be configured to filter routing broadcasts with route maps instead of sending/receiving the entire internet routing table.
BGP Routing Table Components
· Destination IP Address / Subnet Mask
· AS-Path
· Next Hop IP Address

routers are the critical component of all networks and can both security and the security issue to support. A router is essentially multiple network interfaces, the network traffic is transmitted. Or it could be blocked. The router decides when to transmit packets between networks based on internal routing table.
The routing table can also be static. This means that each route is explicitly defined or dynamic where the router learns of new routes through the use of routing protocols.
router also supports access control lists that specify which packets to allow or block. Each packet passes through a router are checked to see if the ACL packet can be transmitted. Many routers today offer security features and functionality of routing. Network segmentation with routers, the amount of data on the segments. It also applies to the broadcast traffic.
routers refuse to allow technicians the ability of some packages explicitly between the segments are transmitted. Use only the internal security features of some
routers can block users on the network of internal telnet access to external systems. Telnet is still a security risk, such as passwords and all communications are transmitted in plain text. For this reason, it is better to establish a telnet session between the internal network and external network. Without a firewall may remove the rule in the router the packet are converted tries bind port 23 to external systems. After all this is done correctly con-figure the ACL on the router. forged packets are packets that contain the IP address in the header is not the actual IP address of the
from the computer. Router fight against it by technicians is the ability to package, remove the cross the interface of the subnet, false. . If the package comes from the external interface of the router using an IP address from the network on the internal interface of the router, the router may need to remove the package and not before. There are two types of access lists available to filter traffic on Cisco routers. One is a standard access list. It allows engineers to traffic from specific addresses or ranges subnet filter. Cisco has also extended ACLs, the technician can filter on a variety of criteria. This access list allows technicians to source addresses, destination addresses and network services to use as the basis of specific filtering rules.
