OSPF Point to Multipoint over Frame Relay

OSPF point to multipoint over FrameRelay

In this lab we’ll use the same topology as in theĀ previousĀ one, where we talked about how to configure OSPF on nonbroadcast network type. In Point to Multipoint OSPF behaves opposite to the Non Broadcast network type, namely here OSPF does not elect a DR/BDR but neighbor discovery proccess takes place. So, in this case we shouldn’t add neighbors manually.

OSPF Non-Broadcast over Frame Relay

OSPF non-broadcast network type over Frame Relay

In this article you we’ll examine how OSPF is behaving when using it over Frame Relay in a Nonbroadcast IP OSPF Network. Nonbroadcast network type is default on Cisco Routers so you don’t have to set it. Take note that in Nonbroadcast network type DR/BDR election process take place but Dynamic Neighbors Discovery don’t, so we need to add neighbors manually. In next picture you see the topology for this lab.
