Configuring Pim Gr (Ipv6) - Huawei Quidway S7700 Configuration Manual - Multicast

Quidway S7700 Smart Routing Switch
Configuration Guide - Multicast
Prune message to the neighbor for re-creating routing entries, thereby ensuring non-stop
forwarding of multicast data on the forwarding plane.
If a dynamic RP is used on the network, after receiving a Hello message with the Generation ID
being changed, the DR or candidate DR unicasts a BSM message to the switch performing active/
standby switchover and the switch learns and restores RP information based on the received
BSM message. If the switch has not leant any RP information from the BSM messages, it obtains
the RP information from the Join/Prune message received from the downstream router and re-
creates multicast routing table.
