To disable Open Shortest Path First (OSPF) maximum transmission unit (MTU) mismatch detection on
receiving Database Descriptor (DBD) packets, use the ip ospf mtu-ignore command in interface
configuration mode. To reset to default, use the no form of this command.
Command Syntax
ip ospf mtu-ignore
no ip ospf mtu-ignore
Default
OSPF MTU mismatch detection is enabled.
Command Mode
Interface configuration
Usage
OSPF checks whether neighbors are using the same MTU on a common interface. This check is
performed when neighbors exchange 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.
Examples
The following example disables MTU mismatch detection on receiving DBD packets:
interface eth-0-1
ip ospf mtu-ignore
