  1. Hi Lee,

    I don’t have a rhyme but there’s some logic to these OSPF network types:

    Only broadcast and non-broadcast require a DR/BDR election since OSPF sees these network types as “multi-access”. Everything with “point” in it is seen as a collection of point-to-point links so there is no DR/BDR election.

    Everything with “non-broadcast” requires you to configure neighbors since OSPF won’t be able to find them by itself.

    Only with point-to-point we use a subnet for each PVC, all other OSPF network types usually have a single IP subnet.

    Have a great day.

    Glad to hear you like it. OSPF will change its timers based on its OSPF network type :slight_smile:

    If you configure the neighbor command on the hub then the spoke routers will receive it and a neighbor adjacency will be formed.
