FAQ-Load Balance and Redundency Backup of PIM-SM Multicast in the Same Domain

Publication Date:  2012-07-27 Views:  38 Downloads:  0
Issue Description
Q: How to realize load balance and redundency backup of PIM-SIM multicast in the same domain? 
Alarm Information
No
Handling Process
A: For the same multicast domain, different multicast groups could realize load balance by registration of different RPs. Moreover, MSDP anycast technology could help realize both load balance and redundency backup. First configure the same RP address for different RPs, and each recipient and multicast source register at a nearest RP, realizing the load balance of RP. MSDP could interact between RPs, which synchronizes the multicast source topology information in the multicast domain for different RP. Thus, if one RP is down, the relevant recipients and sources could switch over to other RPs fast, realizing the backup of RPs.
