Enabling Mld Proxying; Configuring Ipv6 Multicast Forwarding On A Downstream Interface - HP MSR ASM Configuration Manual

Enabling MLD proxying

You can enable MLD proxying on the interface in the direction toward the root of the multicast forwarding
tree to make the device serve as an MLD proxy.
Configuration guidelines
Each device can have only one interface serving as the MLD proxy interface.
•
You cannot 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.
You cannot 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.
• You cannot enable MLD proxying on a VLAN interface with MLD snooping enabled, or vice versa.
Configuration procedure
To enable MLD proxying:
Step
1. Enter system view.
2. Enter interface view.
3. Enable the MLD proxying
feature.
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 interfaces must become 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.
On a shared-media network with more than one MLD proxy device, you cannot 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 shared-media network.
To enable IPv6 multicast forwarding on a downstream interface
Step
1. Enter system view.
2. Enter interface view.
3. Enable IPv6 multicast forwarding
on a non-querier downstream
interface.
