View
MSDP view
Parameter
acl-number: Number of basic or advanced IP ACL, ranging from 2000 to 3999,
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
Use the import-source command to configure which (S, G) entries in the domain
need to be advertised when a MSDP originates an SA message.
Use the undo import-source command to 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
# Specify that the MSDP peer, when creating an SA message, advertises (S,G)
entries with their source addresses in the range of 10.10.0.0/16 and multicast
group addresses in the range of 225.1.0.0/16 in the multicast routing table.
