I have started organizing different parts of my network in separate areas. Most areas come up and distribute all required routes. In two instances, the router on one end shows active interface and neighbor, but on the other side no neighbor shows. I have added the network with the correct area and the dynamic interfaces are up on both routers. This causes no Db to be exchanged. Any Ideas?
Here are the things to check from the wiki and the one thing that isn’t listed there is L3 MTU…it must match on each side of the link.

Two routers do not become neighbors unless the following conditions are met.
Two way communication between routers is possible. Determined by flooding Hello packets.
Interface should belong to the same area;
Interface should belong to the same subnet and have the same network mask, unless it has network-type configured as point-to-point;
Routers should have the same authentication options, and have to exchange same password (if any);
Hello and Dead intervals should be the same in Hello packets;
External routing and NSSA flags should be the same in Hello packets.
Thanks. Will check that.
