export: Specifies to filter SA messages forwarded to the specified MSDP peer.
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-status, import-source.
