  • Page 3: Working Principle

    Operation Manual – MSDP H3C S9500 Series Routing Switches Chapter 1 MSDP Configuration By initiating registration and RPT joining to the nearest RP, MSDP implements RP load sharing. Once an RP turns invalid, its original registered source and receivers will select another nearest RP, implementing redundant RP backup.
  • Page 4 Operation Manual – MSDP H3C S9500 Series Routing Switches Chapter 1 MSDP Configuration message. Besides, the RP in domain 1 encapsulates the first received multicast data into this SA message. If there is any group member in the domain of an MSDP peer (in the figure, it is PIM-SM domain 3), the RP in this domain sends the multicast data encapsulated in the SA message to group members along the RPT and the join message to multicast source.
  • Page 5: Msdp Configuration

    Operation Manual – MSDP H3C S9500 Series Routing Switches Chapter 1 MSDP Configuration If the SA message is sent from a MSDP peer in the same domain, and the peer is the next hop along the optimal path to the RP in the domain of source, it is received and forwarded to other peers (for example, from Switch E to Switch F).

    Operation Manual – MSDP H3C S9500 Series Routing Switches Chapter 1 MSDP Configuration Using rp-policy parameters universally: Multiple static RPF peers take effect at the same time and SA messages are filtered by the RP addresses contained according to the configured prefix list. If multiple static RPF peers using the same rp-policy parameter are configured, any peer that receives an SA message will forward it to the other peers.
