ip ospf mtu-ignore
Use this command to configure OSPF so that it does not check the MTU size during DD (Database Description) exchange.
Use the no form of this command to make OSPF check the MTU size during DD exchange.
Command syntax
ip ospf (A.B.C.D|) mtu-ignore
no ip ospf (A.B.C.D|) mtu-ignore
Parameters
A.B.C.D
IP address of the interface.
Default
By default, during the DD exchange process, OSPF checks the MTU size described in DD packets received from its neighbor. If the MTU size does not match the interface MTU, the neighbor adjacency is not established. Using this command makes OSPF ignore this check and allows establishing of adjacency regardless of MTU size in the DD packet.
Command Mode
Interface mode
Applicability
This command was introduced before OcNOS version 1.3.
Examples
#configure terminal
