MSDP view 

acl-number: Basic or advanced IP ACL number, ranging from 2000 to 3999. An ACL controls SA 

message advertisement by filtering sources (with a basic ACL) and filtering sources or groups (with an 

advanced ACL). If you do not specify this argument, no multicast source is advertised. 

Use the import-source command to specify the (S, G) entries in this domain that need to be advertised 

when an MSDP peer creates an SA message.  

Use the undo import-source command to cancel the configuration. 

By default, an SA message advertise any (S, G) entries in the domain. 

In addition, you can use the peer sa-policy import command or the peer sa-policy export command 

to filter forwarded SA messages. 

# Configure the MSDP peer to advertise only the (S, G) entries for multicast sources in the range of 

10.10.0.0/16 and multicast groups in the range of 225.1.0.0/16 when creating an SA message.
