Information
ip ospf mtu-ignore
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.
Force10 Networks recommends keeping only one key per interface.
