Authentication
OSPF protocol exchanges can be authenticated so that only trusted routing devices can participate.
This ensures less processing on routing devices that are not listening to OSPF packets.
OSPF allows packet authentication and uses IP multicast when sending and receiving packets.
Routers participate in routing domains based on pre-defined passwords. BLADE OS supports
simple password (type 1 plain text passwords) and MD5 cryptographic authentication. This type of
authentication allows a password to be configured per area.
Figure 23 shows authentication configured for area 0 with the password test. Simple authentication
is also configured for the virtual link between area 2 and area 0. Area 1 is not configured for OSPF
authentication.
