R211x-HP Flexfabric 11900 IP Multicast Command Reference

220
Parameters
acl6-number: Specifies an IPv6 basic ACL number in the range of 2000 to 2999.
Usage guidelines
The source field in an IPv6 ACL specifies the IPv6 SSM group range. 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.
You can use this command to define an address range of permitted or denied IPv6 multicast groups. If a
packet to an IPv6 multicast group passes the ACL, the multicast mode is IPv6 PIM-SSM. Otherwise, the
multicast mode is IPv6 PIM-SM.

# Configure the IPv6 SSM group range to be FF3E:0:8192::/96.
