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 predefined passwords. Alteon supports simple
password (type 1 plain text passwords) and MD5 cryptographic authentication for OSPF version 2.
This type of authentication allows a password to be configured per area.
Figure 20 - Authentication Example, page 146
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.
