We have been having some headaches with OSPF in our "backbone" area.
About a year ago we started to route our network and began by installing an RB1200 at our largest tower site. Our "core" router is also an RB1200 and resides at our fiber handoff location. We built a dedicated wireless link between the routers and started OSPF. No issues. Both these routers were and still are in the "backbone" area.
Router A is at our fiber handoff
Router B is at our largest tower site
Over the past year we have installed more routers and began to implement multiple areas. All of these new areas are built off of Router B. We have redundancy and never had any issues.
About a month ago we decided to replace the original link from Router A to Router B. We dedicated new IP's and new ports on each router and plugged the links in. I proceeded to disable the network for the original link in /routing ospf network at both Router A and Router B. I then added the new network at both routers. I watched as the original OSPF Interface disappeared from /routing ospf interface and the new interface showed up. This happened on both routers.
Router A shows that the OSPF Interface has one neighbor (router B) but is in Init state with no adjacent neighbors.
Router B shows that the OSPF Interface has zero neighbors.
I cannot get OSPF running. I am forced to still run on our old link to keep things working.
