peer-address: MSDP peer address.  
acl-number: Advanced ACL number, in the range of 3000 to 3999. If you do not provide an ACL number, 
all SA messages carrying (S, G) entries will be filtered off.  
Description 
Use the peer sa-policy command to configure a filtering rule for receiving or forwarding SA messages.  
Use the undo peer sa-policy command to restore the default setting.  
By default, SA messages received or to be forwarded are not filtered, namely, all SA messages are 
accepted or forwarded.  
In addition to controlling SA message receiving and forwarding by using this command, you can also 
configure a filtering rule for creating SA messages using the import-source command.  
Related commands: display msdp peer-statusimport-source.  
Examples 
# Configure a filtering rule so that SA messages will be forwarded to the MSDP peer 125.10.7.6 only if
