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.
