Example
OS10(conf-if-vl-10)# ip ospf hello-interval 30
Supported
Releases
10.2.0E or later
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 (1 to 255).
key Enter a character string as the password (up to 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
Enables OSPF MTU mismatch detection on receipt of DBD packets.
Syntax
ip ospf mtu-ignore
Parameters None
Default Not configured
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 configured on the incoming interface, OSPF adjacency does not establish. The no version of this
command disables the IP OSPF mtu-ignore configuration.
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.
