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
