Parameters
acl-number: Basic or advanced ACL number, in the range of 2000 to 3999. A basic ACL
is used to filter multicast sources, while an advanced ACL is used to filter multicast
sources or multicast groups. If you do not provide this argument in your command, no
multicast source information will be advertised.
 Note:
During ACL matching, the protocol ID in the ACL rule is not checked.
Description
Use the import-source command to configure a rule of creating (S, G) entries.
Use the undo import-source command to remove any rule of creating (S, G) entries.
By default, when an SA message is created, there are no restrictions on the (S, G)
entries to be advertised in it, namely all the (S, G) entries within the domain are
advertised in the SA message.
In addition to controlling SA message creation by using this command, you can also
configure a filtering rule for forwarding and receiving SA messages by using the peer
sa-policy command.
Related commands: peer sa-policy.
