Usage
Information
To change to a different key on the interface, enable the new key while the old key
is still enabled. The Dell Networking OS sends 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 Networking recommends keeping only one key per interface.
NOTE: The MD5 secret is stored as plain text in the configuration file with
service password encryption.

Disable OSPF MTU mismatch detection upon receipt of database description (DBD) packets.
