Configuring Ipv6 Multicast Forwarding On A Downstream Interface - HP A5500 SI Switch Series Configuration Manual

Follow these steps to enable MLD proxying:
To do...
Enter system view
Enter interface view
Enable the MLD proxying feature
NOTE:
Each device can have only one interface serving as the MLD proxy interface.
Do not enable MLD on interfaces with MLD proxying enabled. Moreover, only the mld require-
router-alert, mld send-router-alert, and mld version commands can take effect on such interfaces.
Do not enable other IPv6 multicast routing protocols—such as IPv6 PIM-DM or IPv6 PIM-SM—on
interfaces with MLD proxying enabled, or vice versa. However, the source-lifetime, source-policy,
and ssm-policy commands configured in IPv6 PIM view can still take effect.
Do not enable MLD proxying on a VLAN interface with MLD snooping enabled, or vice versa.
Configuring IPv6 multicast forwarding on a downstream
interface
Typically, to avoid duplicate multicast flows, only queriers can forward IPv6 multicast traffic. On MLD
proxy devices, a downstream interface must be a querier in order to forward IPv6 multicast traffic to
downstream hosts. If the interface has failed in the querier election, you must manually enable IPv6
multicast forwarding on this interface.
Follow these steps to enable IPv6 multicast forwarding on a downstream interface:
To do...
Enter system view
Enter interface view
Enable IPv6 multicast forwarding on
a non-querier downstream interface
CAUTION:
On a multi-access network with more than one MLD proxy devices, do not enable IPv6 multicast
forwarding on any other non-querier downstream interface after one of the downstream interfaces of
these MLD proxy devices has been elected as the querier. Otherwise, duplicate multicast flows might be
received on the multi-access network.
