This is my scenario: one router is receiving the same external route (also the same metric) on AS 1 and AS 2. It chooses one of them to put in the routing table, and the other (in the other AS) is marked with FD inaccessible in the topology table. This is normal behavior (AFAIK).
The problem is that this router has adjacencies with other two routers, one in AS 1 and one in AS 2 and the route marked with FD inaccessible doesn't get propagated in one of those routers. Which is, again, kind of normal (why propagate the route if it has the FD messed up).
Now, is there a way I could propagate the route with FD inaccessible ?
