What are the different OSPF network types and give an example for each ?

Answer 1

Different OSPF network types with their examples are given below:

1. Broadcast Multi-Access – indicates a topology where broadcast occurs.
   Examples include Ethernet, Token Ring, and ATM.

2. Point-to-Point – indicates a topology where two routers are directly connected.
   An example would be a point-to-point T1.

3. Point-to-Multipoint – indicates a topology where one interface can connect to multiple destinations. Each connection between a source and destination is treated as a point-to-point link.
   An example would be Point-to-Multipoint Frame Relay.

4. Non-broadcast Multi-access Network (NBMA) – indicates a topology where one interface can connect to multiple destinations; however, broadcasts cannot be sent across a NBMA network.
   An example would be Frame Relay.
