Configuring Ipv6 Pim Snooping - HPE FlexNetwork 5130 EI Series Configuration Manual

b. Broadcasts all other types of received IPv6 PIM messages except PIM hello messages in
the VLAN.
c. 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,
can receive all multicast data and all IPv6 PIM messages except IPv6 PIM hello messages.
•
When the Layer 2 switch runs both MLD snooping and IPv6 PIM snooping, it performs the
following actions:
a. Examines whether an IPv6 PIM router is interested in the multicast data destined for a
multicast group according to the received IPv6 PIM messages that the router sends.
b. Adds only the ports that connect to the router and are interested in the data to an IPv6 PIM
snooping routing entry.
c. Forwards IPv6 PIM messages and the multicast data only to the router according to the
multicast forwarding entry, which saves network bandwidth.
For more information about MLD snooping and the router port, see
IPv6 PIM snooping can run in IPv6 PIM-SM and IPv6 PIM-SSM networks. Do not configure IPv6 PIM
snooping in IPv6 PIM-DM or IPv6 BIDIR-PIM networks.

Configuring IPv6 PIM snooping

To configure IPv6 PIM snooping for a VLAN, enable MLD snooping globally on the Layer 2 device,
and enable MLD snooping and IPv6 PIM snooping for the VLAN.
After you enable IPv6 PIM snooping for a VLAN, IPv6 PIM snooping works only on the member
interfaces of the VLAN.
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 for
the VLAN.
6. Enable IPv6 PIM snooping
for the VLAN.
7. (Optional.) Set the aging
time for the IPv6 PIM
snooping global neighbor
ports on the new master
device in IRF master
election.
8. (Optional.) Set the aging
time for the IPv6 PIM
snooping global
downstream ports and
global router ports on the
new master device in IRF
master election.

A global neighbor port is a Layer
2 aggregate interface that acts as
a neighbor port.
The default setting is 210
seconds.
A global downstream port or a
global router port is a Layer 2
aggregate interface that acts as a
downstream port or router port.
