2: System level 

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.  

 

During ACL matching, the protocol ID in the ACL rule is not checked.  

 

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.  

# Configure the MSDP peer in the public instance to advertise only the (S, G) entries of multicast 

sources on the 10.10.0.0/16 subnet and with multicast group address of 225.1.0.0/16 when creating an 

SA message.
