ospf [<ip-address>] message-digest-key “ restores the default value
Parameter: <ip-address> is the interface IP address show in dotted decimal
notation; ranges between 1-255; is the OSPF key.
Default: MD5 key not configured
Command Mode: Interface Mode
Usage Guide: MD5 key encrypted authentication is used for ensure the safety between
the OSPF routers on the network. Same key id and key should be configured between
neighbors when using this command or else no adjacent relationship will not be created.
The last configuration of this command will overwrite the previous one to prevent the
system from communicating with the former key id.
Example:
Switch#config terminal
Switch(config)#interface vlan 1
Switch(Config-if-Vlan1)#ip ospf message-digest-key 2 MD5 yourpassword
13.6.3.24 ip ospf mtu
Command: ip ospf mtu
no ip ospf mtu
Function: Specify the mtu value of the interface as the OSPF group structure according;
the “no ip ospf mtu” command restores the default value.
Parameter: is the interface mtu value ranging between 576~65535.
Default: Use the interface mtu acquired from the kernel.
Command Mode:
Interface Mode
Usage Guide: The interface value configured by this command is only used by OSPF
protocol other than updated into kernel.
Example:
Switch#config terminal
Switch(config)#interface vlan 1
Switch(Config-if-Vlan1)#ip ospf mtu 1480
13.6.3.25 ip ospf mtu-ignore
Command: ip ospf <ip-address> mtu-ignore
no ip ospf <ip-address> mtu-ignore
Function: Use this command so that the mtu size is not checked when switching DD;
the “no ip ospf <ip-address> mtu-ignore” will ensure the mtu size check when
performing DD switch
Parameter: <ip-address> is the interface IP address show in dotted decimal
notation
