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.
