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. ENOS supports simple password (type 1 plain text passwords) and
MD5 cryptographic authentication. This type of authentication allows a password
to be configured per interface.
We strongly recommend that you implement MD5 cryptographic authentication as
a best practice.
Figure 51 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.
