HP A6600 Configuration Manual page 280

The multicast ipv6 boundary command filters IPv6 multicast packets received on an interface. If an
•
IPv6 multicast packet fails to match the IPv6 ACL rule of this command, IPv6 PIM will create no
routing entry.
In addition, the source-policy command in IPv6 PIM filters received IPv6 multicast packets. If an IPv6
•
multicast packet fails to match the IPv6 ACL rule of this command, IPv6 PIM will not create a routing
entry, either.
Solution
Use the debugging mfib ipv6 command to display the debugging information. If IPv6 multicast
1.
packets are found to have been discarded because of too small hop limit value, use the display
multicast ipv6 minimum-hoplimit command to view the minimum hop limit required for an IPv6
multicast packet to be forwarded. Use the undo multicast ipv6 minimum-hoplimit command on the
concerned interfaces to restore the default hop limit setting, or configure multicast packets to be sent
with a higher hop limit value from the multicast source.
Use the display current-configuration command to display the IPv6 ACL rule configured on the
2.
multicast forwarding boundary. Change the IPv6 ACL rule used in the multicast ipv6 boundary
command so that the source address of the IPv6 multicast packets and the IPv6 multicast group
address can both match the IPv6 ACL rule.
View the configuration of the multicast filter. Use the display current-configuration command to view
3.
the configuration of the IPv6 multicast filter, and change the IPv6 ACL rule used in the source-policy
command so that the source address of the IPv6 multicast packets and the IPv6 multicast group
address can both match the IPv6 ACL rule.
