OSPF Network Types - Broadcast

OSPF Network Types - Broadcast 1. Broadcast (Broadcast multi-access network) - Default for Ethernet interfaces. 2. Non-broadcast (Non-Broadcast Multi-Access (NBMA) network) - Exampple is a frame relay network which does not support multicast and broadcast. 3. Point-to-point - Can be configured regardless of the underlying technology (even on Ethernet interfaces). 4. Point-to-multipoint - Useful with frame relay networks that support “pseudo-broadcast”. 5. Point-to-multipoint Non-broadcast - Can be used in frame relay networks where pseudo-broadcast is not supported.
