Hmm.... Maybe we should take a look at Switch B'srouting table:BR-SwitchB#show ip routeTotal number of IP routes: 3Start index: 1 B:BGP D:Connected R:RIP S:Static O:OSPF*:Candidate defaultDestination NetMask Gateway Port Cost Type1 192.168.1.0 255.255.255.252 0.0.0.0 1 1 D2 192.168.2.0 255.255.255.252 0.0.0.0 2 1 D3 172.17.0.0 255.255.0.0 0.0.0.0 v20 1 DWow, Switch B has three routes! Did you see that? They're all connectedroutes. Do you see a route for the 172.18.0.0/16 network? You don't?Hmmm... Are you sure? Rats, you're right. Switch A knows to send 172.18.0.0/16 traffic to Switch B, but Switch B doesn't know how to get to 172.18.0.0/16.Let's fix that.BR-SwitchB#conf tBR-SwitchB(config)#ip route 172.18.0.0 255.255.0.0192.168.2.1We used Switch C's address of 192.168.2.1. Does Switch B know how to get to192.168.2.0/30? Sure. It's a connected route. And we know Switch C knowshow to get to 172.18.0.0/16, because that's a connected route. Why don't wehave Host A send a ping to Host C?Switch AICMP Echo Host Ce1192.168.1.1/30Switch Be2192.168.2.2/30ICMP Echo Host C?Switch CICMP Echo Host Cve 10172.16.0.1/24e1192.168.1.2/30ve 20172.17.0.1/24e1192.168.2.1/30ICMPEcho ReplyHost AICMP Echo Host Cve 30172.18.0.1/24Host A172.16.0.10/24Host B172.17.0.10/24Host C172.18.0.10/24Hurray! We made it all the way to Host C! What's that? Well, that's true. Host Adidn't get a reply to its ping. Looking at the diagram, the reply seems to havegotten stuck at Switch C. Let's take a look at Switch C's routing table:BR-SwitchC#show ip routeTotal number of IP routes: 2Start index: 1 B:BGP D:Connected R:RIP S:Static O:OSPF*:Candidate defaultDestination NetMask Gateway Port Cost Type1 192.168.2.0 255.255.255.252 0.0.0.0 1 1 D2 172.18.0.0 255.255.0.0 0.0.0.0 v30 1 D224 Brocade IP Primer
