Usage Information You can configure a maximum of six digest keys on an interface. Of the available six
digest keys, the switches select the MD5 key that is common. The remaining MD5 keys
are unused.
To change to a different key on the interface, enable the new key while the old key is
still enabled. The system 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, delete the old key. Dell
recommends keeping only one key per interface.

ip ospf mtu-ignore

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