Configuring Ipv6 Pim Snooping - HP A8800 Configuration Manual

other types of received IPv6 PIM messages in the VLAN, and forwards all multicast data to all router
ports in the VLAN. Each IPv6 PIM-capable router in the VLAN, whether interested in the multicast
data or not, will receive all multicast data and all IPv6 PIM messages except for IPv6 PIM hello
messages.
• If the Layer 2 switch runs both MLD snooping and IPv6 PIM snooping, it determines whether an IPv6
PIM-capable router is interested in the multicast data addressed to a multicast group according to
the received IPv6 PIM messages that the router sends, and adds the port that connects to the router
to a multicast forwarding entry. Then, the Layer 2 switch can correctly forward IPv6 PIM messages
and the multicast data only to the router according to the multicast forwarding entry, saving network
bandwidth.

Configuring IPv6 PIM snooping

Before configuring IPv6 PIM snooping for a VLAN, be sure to enable MLD snooping globally and
specifically for the VLAN.
After you enable IPv6 PIM snooping in a VLAN, IPv6 PIM snooping works only on the member interfaces
of the VLAN.
IPv6 PIM snooping does not work in the sub-VLANs of a multicast VLAN. For more information about IPv6
multicast VLAN, see
To configure IPv6 PIM snooping:
Step
1. Enter system view.
2. Enable MLD snooping
globally and enter MLD
snooping view.
3. Return to system view.
4. Enter VLAN view.
5. Enable MLD snooping in the
VLAN.
6. Enable IPv6 PIM snooping in
the VLAN.
