8.4.2 Configuring the Transmission and Filtering of SA Request Messages
After you enable the sending of SA request messages, when a router receives a Join
message, it sends an SA request message to the specified remote MSDP peer, which
responds with an SA message that it has cached. After sending an SA request
message, the router will get immediately a response from all active multicast sources.
By default, the router does not send any SA request message to its MSDP peers upon
receipt of a Join message; instead, it waits for the next SA message.
The SA message that the remote MSDP peer responds with is cached in advance;
therefore, you must enable the SA message caching mechanism in advance. Typically,
only the routers caching SA messages can respond to SA request messages.
After you have configured a rule for filtering received SA messages, if no ACL is
specified, all SA request messages sent by the corresponding MSDP peer will be
ignored; if an ACL is specified, the SA request messages that satisfy the ACL rule are
received while others are ignored.
