摘要:
A device may determine multicast information associated with participating in a multicast. The multicast information may include a virtual rendezvous (RP) address and may identify a multicast group. The device may identify a primary RP address and a secondary RP address associated with the multicast group. The primary RP address may identify a primary RP device and the secondary RP address may identify a secondary RP device. The device may identify an active RP device. The active RP device may be the primary RP device or the secondary RP device. The device may replace the virtual RP address, included in the multicast information, with information that identifies the active RP device. The information that identifies the active RP device may be the primary RP address or the secondary RP address. The device may participate in the multicast based on the information that identifies the active RP device.
