Syntax

no ip ospf mtu-ignore

Command Default

Usage Guidelines

In default operation, the IP MTU on both sides of an OSPFv2 link must be the same, and a check of the MTU is performed when Hello packets are first exchanged.

The no form of the command disables MTU-match checking on a specific interface.

Examples

The following example disables MTU-match checking on a specific OSPFv2 Ethernet interface.

device# configure terminal
device(config)# interface ethernet 1/1
device(conf-if-eth-1/1)# no ip ospf mtu-ignore
