Parameters
acl6-number: Specifies an IPv6 advanced ACL, in the range of 3000 to 3999.
Usage guidelines
This command guards against C-RP spoofing.
In an ACL, the source field specifies the legal C-RP IPv6 address range, and the destination field specifies
the IPv6 multicast group range to which the C-RP is designated. If you specify a VPN instance in the ACL,
the ACL does not take effect. The other optional parameters except time-range are ignored.
The crp-policy command filters the IPv6 multicast group ranges advertised by C-RPs based on the group
prefixes. For example, if the IPv6 multicast group range that a C-RP advertises is FF0E:0:1::/96 but the
IPv6 multicast group range that the crp-policy command defines is FF0E:0:1::/120, the IPv6 multicast
group range FF0E:0:1::/96 can pass.
Examples
# Configure the legal C-RP address range to 2001::2/64 and the IPv6 multicast group range to which
the C-RP is designated to FF03::101/64, so that only devices in the address range of 2001::2/64 can be
C-RPs for the IPv6 multicast group range FF03::101/64.
