ip ospf message-digest-key
Enables OSPF MD5 authentication and sends an OSPF message digest key on the interface.
Syntax
ip ospf message-digest-key keyid md5 key
Parameters
● keyid — Enter an MD5 key ID for the interface, from 1 to 255.
● key — Enter a character string as the password. A maximum of 16 characters.
Defaults Not configured
Command Mode INTERFACE
Usage
Information
All neighboring routers in the same network must use the same key value to exchange OSPF information.
The no version of this command deletes the authentication key.
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
Disables MTU size detection on received Database Descriptor (DBD) packets when forming OSPFv3 adjacency.
Syntax
ip ospf mtu-ignore
Parameters None
Default Not configured
Command Mode INTERFACE
Usage
Information
If the MTU size of the peer interface is greater than the local interface, switches that run OSPF do not
form adjacencies with neighbors. Use this command to override this behavior and form adjacency.
If you try to disable a neighborship using the no ip ospf mtu-ignore command after a neighborship
is formed using the ip ospf mtu-ignore command, the neighborship still continues. To remove a
neighborship after it is formed using the ip ospf mtu-ignore command, use the clear ipv6
ospf process command.
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
