Configuring OSPF Stub Areas

Stub areas do not receive information on external routes. Instead, the Area Border
Router (ABR) generates a default external route into the stub area for destinations
outside the Autonomous System (AS). A stub area allows a default route, intra-area
routes, and inter-area routes, but disallows autonomous system (AS) external routes,
virtual links, and autonomous system boundary router (ASBR) routes.
Use the following steps to configure a stub area:
11-6
MOT (config-if)#ip ospf authentication-key <WORD>
where:
WORD is the unencrypted (clear text) with 1 to 8 characters.
Configuration mode.
OSPF area authentication that permits (cleartext) password protection against
unauthorized access to an area:
MOT (config-ospf)#area <0-4294967295> authentication
where:

Use the area authentication message-digest command in Router Configuration
mode to enable OSPF area authentication that provides encrypted MD5 password
protection against unauthorized access to an area:
MOT (config-ospf)#area <0-4294967295> authentication message-digest
where:
0-4294967295 is the area number.
