I am trying to deploy OSPFv3 across our network. However a few routers do not install the OSPFv3 route's to their routing tables. For example, this router is able to ping a certain host on the network.

However, the router that is a neighbor of the above router (1 hop further away) is unable to reach this network, even though the network is in it's ospf database.

The above 2 routers have an ajecency on VE15 which is in the full state.

I have already tried clearing the OSPFv3 process, however no luck here. I have also enabled OSPFv3 debugging, the debug output contained the following info (filtered on the ipv6 address and router id):

It seems the 2 routers are not properly neighboring, could anyone point me in the right direction as to fixing this issue?
