Hello everybody,

I am facing a problem with ospf neighbor to established
the neighborship is stuck in Exstart phase
and when I debug it . if found the problem with MTU between a router and
switch
here is the ropology SW1 --- R1

r1(config-if)#mtu 1504
% Interface FastEthernet0/0 does not support user settable mtu.

SW1#sh int fa0/1 | in MTU
  MTU 1504 bytes, BW 100000 Kbit, DLY 100 usec

R1#sh int fa0/0 | in MTU
  MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,

any ideas?

Thanks
