A network architect is designing a multi-area OSPF network. What is the strict requirement regarding Area 0?
Answers
AArea 0 must contain the ASBR
BAll other areas must connect directly to Area 0
CArea 0 cannot contain summary LSAs
DArea 0 must use authentication
Correct answer: B — All other areas must connect directly to Area 0
In OSPF, Area 0 is the backbone. All non-backbone areas must physically (or logically via virtual link) connect directly to Area 0 to prevent routing loops.
