Huawei Technologies Proprietary
8-13
The SA message that the remote MSDP 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.

By default, a router receives
all SA request messages
from the MSDP peer.
8.4.3 Configuring a Rule for Filtering the Multicast Sources of SA Messages
An RP filters each registered source to control the information of active sources
advertised in the SA message. An MSDP peer can be configured to advertise only the
(S, G) entries in the multicast routing table that satisfy the filtering rule when the MSDP
creates the SA message, that is, to control the (S, G) entries to be imported from the
multicast routing table to the PIM-SM domain. If the import-source command is
executed without the acl keyword , no source will be advertised in the SA message.
