Configuring the Period for an Interface to Keep the Prune State

The period for an interface to keep the prune state can be set either globally or on an interface. After the period expires, the pruned interface starts to forward messages again. If the multicast device receives a State-Refresh message before the period expires, it resets the timer, that is, it refreshes the prune state.

Prerequisites

Before adjusting control parameters for prune, complete the following tasks:

Configuring a unicast routing protocol
Configuring Basic PIM-DM Functions

Procedure

Global Configuration
1. Access the system view.
  system-view
2. Access the PIM view.
  pim [ vpn-instance vpn-instance-name ]
3. Set the period during which the downstream interface is in the Prune state.
  holdtime join-prune interval
  
  After the period expires, the pruned interface starts to forward packets again. Before the period expires, the FW refreshes the Prune state when receiving a State-Refresh message.
Configuration on an Interface
1. Access the system view.
  system-view
2. Access the interface view.
  interface interface-type interface-number
3. Set the period during which the downstream interface is in the Prune state.
  pim holdtime join-prune interval
  
  After the period is expired, the pruned interface starts to forward packets again. Before the period expires, the FW refreshes the Prune state when receiving a State-Refresh message.
