Parameters
acl-number
: Specifies a basic or advanced ACL number, in the range of 2000 to 3999. A basic ACL
filters multicast sources, and an advanced ACL filters multicast sources or multicast groups. If you do not
provide this argument in your command, no multicast source information is advertised.
Description
Use
import-source
to configure a rule of creating (S, G) entries.
Use
undo import-source
to remove any rule of creating (S, G) entries.
By default, when an SA message is created, no restrictions are defined for the (S, G) entries to be
advertised in it. Namely, all the (S, G) entries within the domain are advertised in the SA message.
During ACL matching, the protocol ID in the ACL rule is not verified.
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.

# Configure the MSDP peer to advertise only the (S, G) entries of multicast sources on the 10.10.0.0/16
subnet and with a multicast group address of 225.1.0.0/16 when creating an SA message.
