ip ospf mtu-ignore
This command disables OSPF maximum transmission unit (MTU) mismatch detection on an interface or range
of interfaces. OSPF Database Description packets specify the size of the largest IP packet that can be sent
without fragmentation on the interface. When a router receives a Database Description packet, it examines the
MTU advertised by the neighbor. By default, if the MTU is larger than the router can accept, the Database
Description packet is rejected and the OSPF adjacency is not established.
no ip ospf mtu-ignore
This command enables the OSPF MTU mismatch detection.
