Parameters
acl-number: Specifies an IPv4 basic ACL number in the range of 2000 to 2999.
Usage guidelines
Use an IPv4 basic ACL to filter hello messages based on the source addresses. If you specify a VPN
instance in the ACL, the ACL does not take effect. The other optional parameters except the time-range
keyword and the fragment keyword are ignored.
Examples
# Configure a legal source address range for hello messages on VLAN-interface 100 so that only the
devices on the 10.1.1.0/24 subnet can become PIM neighbors of this switch.
