Download Documentation Community Marketplace. Catalyst 3750G-24TS-1U Switch Expand All. OSPF has an administrative distance of 110.What is GNS3 Workbench & can it be installed in. IGRP has an administrative distance of 100. (For your information, EIGRP has an administrative distance of 90. If you configure a static route pointing to an exiting interface (for example: “ip route 172.16.0.0 255.255.0.0 s0/0” on R0) then the AD will not be shown. The router treats a static route pointing to an interface the same as a connected interface so the its AD is 0. Of 1 so in the outputs above you will see the administrative distance of both static routes are 1. Static routes have an administrative distance Administrative distance is the value from 0 to 255.ĭirectly connected routes have an administrative distance of 0. The route with the lowest administrative distance value is the preferred route that the router selects. The administrative distance is a measure of trustworthiness where lower numbers are considered to be more trustworthy than higher numbers. But what is ? Well, 1 is the administrative distance (AD) and 0 is the metric of that static route. These parameters are straightforward and easy to understand. The networks 10.0.0.0/8 and 172.16.0.0/16 are the destinations of this static route and if the routers want to reach them they must send packets to 12.12.12.1 (on R1) and 12.12.12.2 (on R2). The “S” letter tells us this is a static route. (Note: In fact, R0 can successfully ping R1 right after adding the static route to R0)Īdministrative distance of a static route.Īfter adding two static routes in R0 & R1 routers, the routing tables of two routers contain these lines: It means we have to add static route to both R0 and R1 so that R0 and R1 can communicate. So there are 2 networks that are directly connected to R0: 10.0.0.0/8 and 12.12.12.0 The letter “C” means “connected” or “directly connected”. Now if we check the routing table of R0 & R1 by the command show ip route on both R0 and R1 We will use two loopback interfaces to simulate two Ethernet LANs. In GNS3, place 2 routers and connect them as the image below, I used IOS to save some RAM (only require 64MB/router). After careful consideration you decided to connect them via static route. As the administrator of the network, you are tasked to connect them so that employees in the two LANs can communicate with each other. Suppose that your company has 2 branches located in New York and Chicago. Now we consider a real-world example of static routing. + exit-interface: the local interface of this router where the packets will go out + next-hop-IP-address: the IP address of the receiving interface on the next-hop router + subnet mask: subnet mask of the destination network + destination-network-address: destination network address of the remote network Ip route destination-network-address subnet-mask In ROUTE 642-902 you will learn about dynamic routing protocols such as OSPF, EIGRP and BGP (RIP is also a dynamic routing protocol but it is not mentioned in ROUTE). With dynamic routes, routers can communicate with each other to exchange routing information. Dynamic routes, on the other hand, use a routing protocol to determine the best path and the routes can be changed depending on specific parameters (like bandwidth, delay, cost…). Static route is often used when your network has only a few routers or there is only one route from a source to a destination. Static route tells the device exactly where to send traffic, no matter what. In this tutorial we will connect two routers via static route with GNS3.
