Configuring SA message policies
To control the propagation of multicast source information, you can configure the following policies:
•
SA creation policy—Limits the multicast source information advertised in SA messages. This
policy enables the router to advertise (S, G) entries based on the used ACL that specifies the
multicast sources and groups.
•
SA incoming or outgoing policy—Limits the receipt or forwarding of SA messages. This
policy enables the router to receive or forward SA messages based on the used ACL that
specifies the multicast sources and groups.
By default, multicast data packets are encapsulated in SA messages and forwarded to MSDP peers
only if the TTL values in the packets are larger than zero. You can set the lower TTL threshold for
multicast data packets encapsulated in SA messages that are sent to an MSDP peer. Then, only
multicast data packets whose TTL values are larger than or equal to the configured value are
encapsulated in SA messages. Only SA messages whose TTL values are larger than or equal to the
configured value are forwarded to the specified MSDP peer. This controls the multicast data packet
encapsulation and limits the propagation range of the SA messages.

N/A
By default, after receiving a
new join message, a device
does not send an SA request
message to any MSDP peer.
Instead, it waits for the next SA
message from its MSDP peer.
By default, no SA request
policies exist, and all SA
request are permitted.
