Hi

Lets talk MPLS,okay so how to let the switch deal with jumbo frame specially when u adjust the mtu size under the interface to 1512..

What is the command to do that?

v  So what's happened to ospf tough?do I need to config under the interface the command: [ip ospf mtu-ignore]

Thanks

Good day Alsayed,

The answer to your question is dependent upon what kind of hardware you are changing the MTU on.  Some switches allow interface level modification, while others require a system wide change, which often requires a reboot to take effect.  The link below has information about jumbo and giant frame support on different switching hardware.  I hope that helps.
