N00b: connecting 3660 routers..

[eliotB]

Hi!

I can't believe this...I'm stuck on such a simple thing.

I have two 3660 routers.

R1(fa0/0.ip)R1(fa1/10.noip)--cable-->R2(fa0/1.ip)

R1 has a 16 port Ethernet module in slot 1. I have a cable going from fa1/10 on R1 to fa0/1 on R2.

fa0/1 on R2 has an ip address, but fa1/10 does not due to being a L2 port(I can't set one even if I try). Finally, I have port fa0/0 on R1 configured w/an IP address.

The ip address on fa0/0 of R1 and fa0/1 on R2 are in the same subnet.

I want to ping fa0/1 port on R2 from R1 fa0/0 visa versa. For whatever reason I can not. I assumed that the pings would get forwarded onto port fa0/0 since fa1/10 is on the same switch.

Why isn't it working?

Thanks!

Use a crossover between the fa0/0 on R1 and fa0/1 on R2. I do no know those routers, but I imagine the fa1/10 does not need an IP address unless you do VLANs. Post a sh int and a sh ver.

Ya, I could use a crossover but that'd be too easy

I'm not understanding why the current setup is not working.

Post sh int, not sh int fa0/1...and post sh ver so I can understand what interfaces are associated with what.

1. Is this some type of lab experiment?

2. Unless the both cables from the Ethernet port of the routers are plugged into the same switch it simply wont work.

3. Port 1/10 is in vlan 1 by default and unless vlan 1 has a routable ip address it cant route to the other ethernet interface.

Please post a show run of both routers.
