I would suspect the cable being bad if they have confirmed the frame switch
and you are configured the way you have described.
Did they try to swap the cable?

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.
