I created a simple packet tracer topology and connected three ospf areas in the next manner: area0 - area1 - area2 . I verified that area 2 couldn't ping the rest of the network thus I configured a virtual link through area 1. Now area 2 is connected to area 0. My question is why area 1 sees area 2 in its routing table but area 2 cannot see area 1?
Some ip route results:
