Configuring the Maximum Number of Downstream Nodes in a Multicast Forwarding Entry

Configuring the Maximum Number of Downstream Nodes in a Multicast Forwarding Entry


When the router receives a multicast packet, it copies the packet for each downstream node in the matching multicast forwarding entry. If there are too many downstream nodes, the router is overloaded. To reduce the load on the router, limit the number of downstream nodes in each multicast forwarding entry.

Default Settings

By default, a multicast forwarding entry can contain a maximum of 128 downstream nodes.


  1. Run system-view

    The system view is displayed.

  2. Run multicast forwarding-table downstream-limit limit

    The maximum number of downstream nodes in a multicast forwarding entry is configured.
