Hi Group,
Consider the following situation in OSPF area 0:
CAT_3550 (Interface Vlan1) ................(Ethernet0) R1
Interface Vlan1 - MTU Size: 1504 bytes
Interface E0 - MTU Size: 1500 bytes
In this situation there is an MTU mismatch between neighbors. To solve it, I
can use the command
IP OSPF MTU-IGNORE in both interfaces. Otherwyse, the neighbor relationship
will not form.
Am I correct ? There is another way to do the same thing ?
Regards,
CAT3550#sh int vlan 1
