Connectivity Guide
Example
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# ip ospf message-digest-key 2 md5 sample12345
Supported Releases 10.3.0E or later
ip ospf mtu-ignore
Enables OSPF MTU mismatch detection on receipt of DBD packets.
Syntax
ip ospf mtu-ignore
Parameters None
Default Not congured
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 congured on the incoming
interface, OSPF adjacency does not establish. The no version of this command disables the IP OSPF mtu-ignore
conguration.
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
Congures 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 congured
Command Mode INTERFACE
Usage Information You must congure the interface before setting the interface to Passive mode. The no version of the this
command disables the passive interface conguration.
