Configuring the switchover to SPT

Restrictions and guidelines

Some devices cannot encapsulate multicast data in register messages destined to the RP. As a best practice to avoid multicast data forwarding failures, do not disable the switchover to SPT on C-RPs that might become the RP.

Procedure

  1. Enter system view.

    system-view

  2. Enter PIM view.

    pim [ vpn-instance vpn-instance-name ]

  3. Configure RPT to SPT switchover.

    spt-switch-threshold { immediacy | infinity } [ group-policy ipv4-acl-number ]

    By default, the first multicast data packet triggers the RPT to SPT switchover.
