Hi Ajay,
You'll notice that the OSPF protocol RFCs do not specify the behavior
for dynamic configuration. Obviously, the goal should be to handle
changes as dynamically as possible while insuring correct operation.
In this spirit, many implementations do force neighbor adjacencies on
the changed interface back to EXCHANGE-START when there is an MTU
change. An interface MTU change should be a rare event.
Hope this Helps,
Acee

Hi all,
I have doubt about MTU change event. OSPF DDPacket sends interface
MTU & if interface MTU matches then only router forms adjacency
with neighbor. But once adjacency comes up fine & interface MTU
changes then what is suggested behavior ?
Do we have to destroy the adjaceny ? or Do nothing ?
Thanks
Ajay
