routing with crossover cables

Feb 09, 2007 2 Replies

Hello all thanks in advance for any help. I bought four routers I plan on using for the ccna and ccnp exams. Although I have four routers in my new lab, I have solely one serial cable and just ordered two more so my question is as follows: Has anyone used their ethernet ports with crossover cables for routing (eigrp, bgp) is this even doable or can I do something with a switch to get some practice while I wait for my cables?



Here is my example; all of my routers have ethernet ports I'll call them RAe0 = RouterA_Ethernet0, RB = RouterB_Ethernet0, etc.



RAe0 int eth0 ip address 5.6.7.1 ip routing router eigrp 22 network 1.2.3.0 255.255.255.0 neighbor 5.6.7.2



RBe0 int eth0 ip address 5.6.7.2 ip routing router eigrp 22 network 9.10.11.0 255.255.255.0 neighbor 5.6.7.3



RCe0 int eth0 ip address 5.6.7.3 ip routing router eigrp 22 network 12.13.14.0 255.255.255.0 neighbor 5.6.7.4



RDe0 int eth0 ip address 5.6.7.4 ip routing router eigrp 22 network 21.22.23.0 255.255.255.0



Is this doable until I get my serial cables? Or can I somehow use a switch to get them to pass routing information into their ethernet interfaces. Any help is sincerely appreciated.



The routing information will pass over the ethernet interfaces.

Much of the routing protocol behaviour is independent of whether you have a broadcast, non-broadcast or point to point media.

I would imagine for example that BGP just won't care at all, ever. RIP doesn't care, OSPF and (EIGRP I think) have some differences.

You can learn a lot (nearly everything) from using Ethernet alone.
