ip ospf mtu-ignore

Enables or disables maximum transmission unit (MTU) match checking.
Syntax
ip ospf mtu-ignore
no ip ospf mtu-ignore
Command Default

Enabled

Interface subtype configuration mode

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 re-enables MTU-match checking on a specific interface if it has been disabled.

Examples

The following example disables MTU-match checking on a specific OSPFv2 Virtual Ethernet (VE) interface. 

device# configure terminal
device(config)# interface interface ve 1
device(config-vif-1)# ip ospf mtu-ignore

The following example re-enables MTU-match checking on a specific OSPFv2 Virtual Ethernet (VE) interface.
