Which OSPF network types are compatible and allow communication through the two peering devices?
- A. point-to-multipoint to nonbroadcast
- B. broadcast to nonbroadcast
- C. point-to-multipoint to broadcast
- D. broadcast to point-to-point
Explanation: The following different OSPF types are compatible with each other:
+ Broadcast and Non-Broadcast (adjust hello/dead timers)
+ Point-to-Point and Point-to-Multipoint (adjust hello/dead timers)
Broadcast and Non-Broadcast networks elect DR/BDR so they are compatible. Point-topoint/ multipoint do not elect DR/BDR so they are compatible.
