ip ospf mtu-ignore

To disable OSPF MTU mismatch detection on receiving DBD packets, use the ip

ospf mtu-ignore command in interface configuration mode. To reset to default,

use the no form of this command.

ip ospf mtu-ignore

no ip ospf mtu-ignore

Syntax

Description

None.

Default OSPF MTU mismatch detection is enabled.

Command Mode Interface configuration.

Usage Guideline OSPF checks whether neighbors are using the same MTU on a common

interface. This check is performed when neighbors exchange Database

Descriptor (DBD) packets. If the receiving MTU in the DBD packet is higher than

the IP MTU configured on the incoming interface, OSPF adjacency will not be

established.

Example The following example disables MTU mismatch detection on receiving DBD

packets.

Switch# configure terminal

Switch(config)# interface vlan1

Switch(config-if)# ip ospf mtu-ignore
