IP OSPF MTU-IGNORE
Syntax
ip ospf (A.B.C.D) mtu-ignore
no ip ospf (A.B.C.D) mtu-ignore
Parameters
A.B.C.D Specifies the IP address of the interface. This is an
optional parameter.
Description
Use the IP OSPF MTU-IGNORE command to configure OSPF so that it
does not check the MTU size during DD (Database Description)
exchange.
By default, OSPF checks the MTU size described in DD packets received
from the neighbor during the DD exchange process. If the MTU size does
not match the interface MTU, neighbor adjacency is not established. Using
this command makes OSPF ignore this check and allows adjacency to be
established regardless of MTU size in the DD packet.
Use the no form of this command to make sure that OSPF checks MTU
size during DD exchange.
Command Mode
Interface mode
Example
The following example sets the OSPF so that it does not check the MTU
size during DD exchange on interface 4:
switch# configure terminal
switch(config)# interface xe4
switch(config-if)# ip ospf mtu-ignore
