OSPF inter-area networks not learned

KOFFIAZOUGO74643 · ‎03-10-2020

I am having problem in ospf. In topology i was trying to connect non-backbone areas for that i created virtual link from 3.3.3.1 to 6.6.6.1 but problem remain same as i am getting routes on all routers except one that is 7.7.7.1 who's having routes of area 0 but not area 50. So please help me to resolve this

Hello,

hard to say without seeing the configs, can you post them ?

What is the output of:

show ip ospf virtual-links

?
