Free Cisco Lab Packet Tracer OSPF Frame-Relay

Posted by: admin  :  Category: CCNA, CCNP

In broadcast multiple-access networks, neighbor adjacency is formed dynamically using multicast hello packets to A DR and BDR are elected normally, and function normally.

For non-broadcast multiple-access networks (NBMA), RFC 2328 defined the following two official modes for OSPF:

  • nonbroadcast.
  • point-to-multipoint.

Cisco has defined the following three additional modes for OSPF in NBMA topologies:

  • point-to-multipoint nonbroadcast.
  • broadcast.
  • point-to-point.


In this lab scenario you will be configuring the OSPF routing process in a single Area to run over frame-relay.You will configure OSPF on all routers of the frame-relay using the point-to-multipoint interface ( subnet). you will advertise all connections in OSPF and verify there connectivity.

This lab scenario has been designed for Packet Tracer but can be completed with GNS3 with the included GNS3 topology, or real hardware from the included network drawing.

    hello all,
    if some body done this lab on PT please can you tell me that how you configure on PT NBMA, as i saw the command was not supported, i can do NBMA on GNS but not on PT

    add “ip ospf network broadcast” to all physical interfaces assigned with ospf and reload all routers. let me know if this doesnt work. thanks.
