After authentication is configured, OSPF only receives packets that pass authentication. Failed packets
cannot establish neighboring relationships.
You must configure the same area authentication mode on all the routers in an area. In addition, the
authentication mode and password for all interfaces attached to the same area must be identical.
To configure OSPF authentication:
