ip ospf ignore-mtu

Use this command to ignore the MTU advertised by the neighbor.

Syntax

ip ospf ignore-mtu
no ip ospf ignore-mtu

Parameters

None.

Defaults

None.

Mode

Configuration command, Interface configuration.

Usage

If the interface MTU field in the Database Description (DBD) packet indicates an ip datagram size that is greater than the router can accept on the receiving side without fragmentation, the DBD packet is rejected. If the ignore MTU feature is enabled with this command, the DBD packet will not be rejected and will be processed instead.

The “no” form of this command disables the ignore MTU feature.

Example

This example shows how to enable the ignore MTU feature on this interface:

System(rw-config)->interface vlan 1
System(rw-config-intf-vlan.0.1)->ip ospf ignore-mtu
