Readmitting or Removing Interfaces

Interfaces rejected for a flow due to insufficient bandwidth are not automatically readmitted, even when bandwidth becomes available again. Rejected interfaces have an opportunity to be readmitted when one of the following occurs:

• The multicast routing protocol updates the forwarding entry for the flow after receiving a join, leave, or prune message or a topology change occurs.
• The multicast routing protocol updates the forwarding entry for the flow due to configuration changes.
• You manually reapply bandwidth management to a specific flow or to all flows using the clear multicast bandwidth-admission operational command.

In addition, even if previously available bandwidth is no longer available, already admitted interfaces are not removed until one of the following occurs:

• The multicast routing protocol explicitly removes the interfaces after receiving a leave or prune message or a topology change occurs.
• You manually reapply bandwidth management to a specific flow or to all flows using the clear multicast bandwidth-admission operational command.

For additional information about the clear multicast bandwidth-admission command, see the JUNOS Routing Protocols and Policies Command Reference.
