Parameters
acl6-number: Specifies an IPv6 basic ACL number in the range of 2000 to 2999.
Usage guidelines
Use an IPv6 basic ACL to filter hello messages based on the IPv6 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 GigabitEthernet 2/1/1, so that only the
devices on the FE80:101::101/64 subnet can become PIM neighbors of this router.
