Instead, it waits for the arrival of SA message ofthe next period.8.2.8 Controlling the Source Information CreatedI. Filtering the multicast routing entries importedRP filters the registered sources to control the information of the active sourcesadvertised in SA message. MSDP peers can be configured to only advertise thequalified (S, G) entries in the multicast routing table when creating SA messages, that is,to control the (S,G) entries imported from the multicast routing table to the domain.Please perform the following configurations in MSDP view.Table 8-8 Filtering the multicast routing entries importedOperation CommandAdvertise only the (S, G) entries permitted bythe ACL import-source [ acl acl-number ]Remove the above configuration undo import-sourceBy default, only intra-domain sources are advertised in SA messages.If the import-source command without acl parameter is executed, no source isadvertised in SA messages.II.
