Syntax ip ospf message-digest-key keyid md5 key To delete a key, use the no ip ospf message-digest-key keyid command. Parameters keyid key Enter a number as the key ID. Range: 1 to 255.

Command Modes INTERFACE Command History Usage Information Version 8.3.16.1 Introduced on MXL 10/40GbE Switch IO Module To change to a different key on the interface, enable the new key while the old key is still enabled. The FTOS will send two packets: the first packet authenticated with the old key, and the second packet authenticated with the new key. This process ensures that the neighbors learn the new key and communication is not disrupted by keeping the old key enabled. After the reply is received and the new key is authenticated, you must delete the old key. Dell Force10 recommends keeping only one key per interface. Note: The MD5 secret is stored as plain text in the configuration file with service password encryption. ip ospf mtu-ignore Disable OSPF MTU mismatch detection upon receipt of database description (DBD) packets. Syntax ip ospf mtu-ignore To return to the default, use the no ip ospf mtu-ignore command.
