OSPF - Basic Peering

OSPF and Frame Relay

1.  Match Network types or Interface types 

              - Frame -Relay Interface type ::   Physical , Multipoint, Point-2-Point
              - OSPF :: 5 Network types
 2. Timers won't match if Interfaces types are different.
 3. Remmeber that Broadcast and non-broadcast try to elect DR/BDR.
      - HUB must be DR
 4. Don't forget the "broadcast" statement if you are using frame maps.
