CLI Reference Guide
Use this command to configure the MD5 digest key for OSPF interface. Use the
no command to delete the MD5 key.
Specifies a value for MD5 key identifier.
The value range is 1 to 255.
Specifies up to 16 characters long for the OSPF MD5 message digest key. The
syntax is general string that does not allow space.
By default no MD5 key is configured.
Interface configuration mode
The authentication for OSPF messages can be either operated in password mode or
MD5 digest mode. This command defines the message digest key used by the MD5
digest mode.
In MD5 digest mode, the OSPF message sender will compute a message digest
based on the message digest key for the TX message. The message digest and the
key ID will be encoded in the packet. The receiver of the packet will verify the digest in
the message against the digest computed based on the locally defined message
digest key corresponding to the same key ID.
The same key ID on the neighboring router should be defined with the same key
string.
All the neighboring routers on the same interface must use the same key to
exchange the OSPF packet with each other. Normally, all neighboring routers on the
interface use the same key
Users can verify the settings by entering the show ip ospf interface command.
To set the System interface (vlan 1) authentication type to MD5:
ip ospf message-digest-key
