BSR encapsulates the RP-set information in the bootstrap messages (BSMs) and floods the BSMs to the
entire PIM-SM domain.
Figure 26 Information exchange between C-RPs and BSR
Based on the information in the RP-set, all routers in the network can select the proper RP for a specific
multicast group based on the following rules:
1.
The C-RP that is designated to a smallest group range wins.
2.
If the C-RPs are designated to the same group range, the C-RP with the highest priority wins.
3.
If the C-RPs have the same priority, the C-RP with the largest hash value wins. The hash value is
calculated through the hash algorithm.
4.
If the C-RPs have the same hash value, the C-RP with the highest IP address wins.
