Parameter
acl-number: Number of basic or advanced IP ACL, ranging from 1 to 199,
controlling which sources SA messages will advertise and to which groups it will
be sent in the domain. Basic ACL performs filtering to source and advanced ACL
performs filtering to source/group. If no ACL is specified, no multicast source will
be advertised.
Description
Using the import-source command, you can configure which (S, G) entries in the
domain need to be advertised when a MSDP originates an SA message. Using the
undo import-source command, you can remove the configuration.
By default, all the (S, G) entries in the domain are advertised by the SA message.
Besides controlling SA messages creation, you can filter the forwarded SA
messages by the commands peer sa-policy import and peer sa-policy export.
Example
Configure which (S, G) entries from the multicast routing table will be advertised
in SA messages originated by the MSDP peer.
