Bidir-PIM Application in a Single AS

Bidir-PIM Application in a Single AS

Figure 4-24 illustrates multicast service deployment on a large-scale network. The Interior Gateway Protocol (IGP) is running on the network, and all network segments are reachable. A multicast protocol is required on the network to allow multi-party video conferences among users connected to the network.

Implementation

As shown in Figure 4-24, HostA, HostB, HostC, and HostD need to join a multi-party video conference, and the entire PIM domain runs Bidir-PIM.

The network deployment is as follows:

  1. Enable Bidir-PIM on all routers in the PIM domain.

  2. Enable PIM-SM on all router interfaces so that they can set up PIM neighbor relationships.

  3. Select a router at the meeting point of multicast streams as the RP and configure the RP to serve Bidir-PIM. For example, RouterE in Figure 4-24 can act as the RP.

    Recommended RP deployment is as follows:

    • On small and medium networks, configure a static RP because the static RP is stable and has low requirements on device configurations.

      If a static RP is configured, all routers (including the RP) in the domain must be configured with the same RP information and multicast group range.

    • On large networks, deploy dynamic RP to improve reliability and facilitate maintenance.

    NOTE:

    Do not use both static and dynamic RP configurations in the same PIM domain because this may cause inconsistent RP information on routers.

  4. Run IGMP between RouterA and HostA, RouterB and HostB, RouterC and HostC, and RouterD and HostD.

    All router interfaces on the same network segment must run the same IGMP version (IGMPv2 is recommended) and have the same parameter settings, such as the query intervals and timeout period of group memberships. If router interfaces run different IGMP versions or use different parameter settings, routers cannot maintain consistent IGMP group membership.

  5. After the configurations are complete, routers on the network set up a bidirectional RPT rooted at the RP, and the hosts can communicate in a video conference.

    NOTE:

    To enable user hosts to receive multicast data stably, statically bind the multicast groups requested by user hosts to the interfaces directly connected to the user network segments.
