Hi, I'm having a hard time trying to see the problem here. I don't think
there is one, but I'm doing a lab on a rack rental and this is what's
happening
Rack1R1#sh ip int brief
Interface IP-Address OK? Method Status
Protocol
FastEthernet0/0 unassigned YES unset administratively down
down
Serial0/0 191.1.125.1 YES manual up
down
Serial0/1 unassigned YES unset administratively down
down
the serial int s0/0 is always up down. My config of the routers is below.
All three routers R1, R2 and R5 should be connected to the frame-switch. But
for some reason on R1 the s0/0 protocol on the interface keeps flapping. The
rack rental company said it was a layer 3 issue with my config. I stripped
the config of and reloaded the routers. Then just did the frame stuff again.
I have the same problem with R1's s0/0 interface keeps flapping. Does anyone
have any ideas on what could be wrong here? I can't for the life of me see
what is wrong with my configs. Thanks in advance.
