The problem was that the route that came in thru the BRI interface was from
area 0 (intra-area route) and the route that came thru the Serial interface
came from area 345 (inter-area route).
The BRI interface was a backup of the Serial interface. When the Serial went
down, the BRI went up and the LSA from area 0 came thru the BRI.
The route-map was working OK, so the route that pointed to the BRI was
deleted, but the LSA was still in the OSPF database. It made that the route
thru the Serial was not considered as the best (the route thru the Serial
was an inter-area route and the route thru the BRI was an intra-area route),
and it wasn't included in the route table.
So the route from the BRI was deleted by the route-map and the LSA that came
from the Serial was not considered the best route and was not included in
the routing table. So there was no route in the routing table. This confused
me and made me think that the route-map was deleting all routes, not only
the route thru the BRI interface.
Later i realized that the problem wasn't in the route-map.
