1. Area 0. It's the only area on 1.1.1.1 and 3.3.3.3 with "area n
authentication" configured. The virtual link connects 3.3.3.3 to area
0. Authenticating the virtual link is more or less equivalent to
configuring "ip ospf message-digest-key 1 md5 cisco" on a physical
interface.
2. All routers in the area have to have same authentication
parameters, and e2/0/0 is in area 0.
3. ATM 2/0.20 is in area 1. There's no authentication configured for
area 1.
