Usage Guidelines

Usage Scenario

The source RP encapsulates information about all active sources into multiple SA messages to advertise it. Each SA message contains multiple (S, G) entries.

After the encap-data-enable command is configured on the source's RP, the RP encapsulates the multicast data carried in the Register message into an SA message, and then sends the SA message to the MSDP peer. Only one multicast data packet can be encapsulated into an SA message.

After the encap-data-enable command is configured on the MSDP peer, the switch can transmit the SA messages carrying a multicast data packet between PIM-SM domains.

Prerequisites

MSDP has been enabled using the msdp command.
