I am trying to configure OSPF for my remote sites to connect back to HQ. IPSec VPN tunnels are up and everything works fine until i apply OSPF at the HQ and the remote branches.
The branches seem to come on for 2 minutes and off for 3 minutes and so forth.
When I do a
show ip ospf neighb
command, it shows my remote branches with state as FULL/-. I don't know what that means and how to fix that too.
