ip ospf mtu-ignore
Enables OSPF MTU mismatch detection on receipt of DBD packets.
Syntax
ip ospf mtu-ignore
Parameters None
Default Not congured
Command Mode INTERFACE
Usage Information When neighbors exchange DBD packets, the OSPF process checks if the neighbors are using the same MTU on a
common interface. If the receiving MTU in the DBD packet is higher than the IP MTU congured on the incoming
interface, OSPF adjacency does not establish. The no version of this command disables the IP OSPF mtu-ignore
conguration.
Example
OS10(conf-if-vl-10)# ip ospf mtu-ignore
Supported Releases 10.2.0E or later
ip ospf network
Sets the network type for the interface.
Syntax
ip ospf network {point-to-point | broadcast}
Parameters
• point-to-point — Sets the interface as part of a point-to-point network.
• broadcast — Sets the interface as part of a broadcast network.
Default Broadcast
Command Mode INTERFACE
Usage Information The no version of this command resets the value to the default.
Example
OS10(conf-if-eth1/1/1)# ip ospf network broadcast
Supported Releases 10.2.0E or later
ip ospf passive
Congures an interface as a passive interface and suppresses both receiving and sending routing updates to the passive interface.
Syntax
ip ospf passive
Parameters None
Default Not congured
Command Mode INTERFACE
Usage Information You must congure the interface before setting the interface to Passive mode. The no version of the this
command disables the passive interface conguration.
Example
OS10(conf-if-eth1/1/6)# ip ospf passive
Supported Releases 10.2.0E or later
