Interoperate OSPF Network Types

  1. Broadcast to Broadcast
  2. Non-broadcast to Non-broadcast
  3. Point-to-Point to Point-to-Point
  4. Broadcast to Non-broadcast (adjust hello/dead timers)
  5. Point-to-Point to Point-to-Multipoint (adjust hello/head timers)

Configuring OSPF Network Types in Cisco

In an OSPF routing domain, there can be multiple OSPF network types that can be configured to manipulate the OSPF operations as per the needs and requirements on a specific interface keeping in mind the network topology and the desired output out of it. To do so, one must know the OSPF network types, difference in them, how to configure them on specific interface after configuring OSPF routing in the topology and which are compatible with one another as. Some network types will work with each other, but you will have to adjust the hello/dead timers.
