AREA AUTHENTICATION
area authentication
Overview Use this command to enable authentication for an OSPF area. Specifying the area
authentication sets the authentication to Type 1 authentication or the Simple Text
password authentication (details in RFC 2328).
The no variant of this command removes the authentication specification for an
area.
Syntax area < area-id > authentication [message-digest]
no area < area-id > authentication
Default By default, no authentication occurs.
Mode Router Configuration
Usage All OSPF packets transmitted in this area must have the same password in their
OSPF header. This ensures that only routers that have the correct password may
join the routing domain.
Give all routers that are to communicate with each other through OSPF the same
authentication password.
Use the ip ospf authentication-key command to specify a Simple Text password.
Use the ip ospf message-digest-key command to specify MD5 password.
Example
awplus# configure terminal
awplus(config)# router ospf 100
awplus(config-router)# area 1 authentication
