Configuring the SA Request

If the capacity of the SA cache enabled on the remote MSDP peer is too large, configuring sending SA Request message on the local device can shorten the time taken by a receiver to obtain multicast source information. And you can configure filtering rules for receiving SA Request messages on a specified remote MSDP peer.

Configuring Sending SA Request Messages: When FW receives a new Join message and no corresponding (S, G) entry exists locally or in the Source Active (SA) cache, the FW immediately sends an SA Request message to the specified MSDP peer rather than waits for the SA message in the next period.

(Optional) Configuring the Filtering Rules for Receiving SA Request Messages: You can configure rules for filtering the Source Active (SA) Request messages received from the local FW on a specified remote MSDP peer. If the SA Request message passes the filtering, the peer immediately responds.
