Hi All
I got MTU mismatch, as a result OSPF process is not coming up and also the LDP neighbour. Below is the setup.
Switch1 (MTU 9600) -> L2 Switch (MTU 9600) -> Router (MTU 1500)
The OSPF process and LDP was configured between Switch1 & Router. I understand I can configure "ip ospf mtu-ignore" in switch1 which has higher MTU which will solve the issue? I have 2 interface (loopback and vlan) on same OSPF process ID. Do i need to apply "ip ospf mtu-ignore" on both interface?
Also am looking to migrate VRF's to Switch1 which will communicate to router. Will Switch1 sends higher MTU to router regardless or it will only send higher MTU if a server sends it?
