In an IPv4 basic ACL, the source keyword matches against multicast group addresses in register
messages. In an IPv4 advanced ACL, the source keyword and the destination keyword match against the
multicast source addresses and multicast group addresses in register messages, respectively.
If you specify the vpn-instance keyword in an ACL rule, the rule does not take effect. The other optional
parameters except the time-range keyword and the fragment keyword in the ACL rules are ignored.
This command controls the creation of SA messages. You can also use the peer sa-policy command to
configure a filtering rule to control forwarding and acceptance of SA messages.
Examples
# On the public network, configure an SA creation policy to advertise only the (10.10.0.0/16,
225.1.0.0/16) entries when an SA message is created.
