Hi, At the virtual link line for both routers, add a message-digest authentication, eg: Router A area 1 virtual link 192.168.5.5 message-digest-key 1 md5 pass
The "area 0 auth message-digest" is needed at RouterA also since it is ABR for area 3. HTH > Ran into following during a lab scenario, but can't find any documentation > on this.

(the ABR which is not directly > connected to Area 0.) "area 0 authentication message-digest".
