Page 206: Msdp Overview
Quidway S3700 Series Ethernet Switches Configuration Guide - Multicast 8 MSDP Configuration 8.1 MSDP Overview MSDP functions to set up an MSDP peer relationship between RPs in different PIM-SM domains. MSDP peers exchange (S, G) information by sending SA messages. In this manner, MSDP peers share multicast source information and hosts can receive multicast data from the multicast sources in another PIM-SM domain.
Page 207 Quidway S3700 Series Ethernet Switches Configuration Guide - Multicast 8 MSDP Configuration PIM-SM Intra-Domain Anycast RP After anycast RP is applied to a PIM-SM domain, the multicast source registers with the nearest RP and receivers send Join messages to the nearest RP. This reduces the burden of a single RP, implements RP backup, and optimizes the forwarding path.

Quidway S3700 Series Ethernet Switches Configuration Guide - Multicast 8 MSDP Configuration Setting the TTL threshold can limit the transmission scope of a multicast data packet contained in an SA message.
