HP 6125XLG - Configuring Ipv6 PIM Snooping

235
a. Maintains the router ports according to the received IPv6 PIM hello messages that IPv6
PIM-capable routers send.
b. Floods 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:
d. 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.
e. Adds only the ports that connect to the router and are interested in the data to an IPv6 PIM
snooping routing entry.
f. 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 "Configuring MLD snoop
ing."
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. For more information about IPv6 PIM, see
"Configuring IPv6 PIM."
Configuring IPv6 PIM snooping
Before configuring IPv6 PIM snooping for a VLAN, you must enable MLD snooping globally and 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:

Command Remarks
1. Enter system view.
system-view N/A
2. Enable MLD snooping
globally and enter MLD
-snooping view.
mld-snooping
By default, MLD snooping is
disabled.
3. Return to system view.
quit N/A
4. Enter VLAN view.
vlan vlan-id N/A
5. Enable MLD snooping for
the VLAN.
mld-snooping enable
By default, MLD snooping is
disabled in a VLAN.
6. Enable IPv6 PIM snooping
for the VLAN.
ipv6 pim-snooping enable
By default, IPv6 PIM snooping is
disabled in a VLAN.
7. (Optional.) Set the aging
time for the IPv6 PIM
snooping global neighbor
ports on the new master
device in IRF master
election.
ipv6 pim-snooping graceful-restart
neighbor-aging-time interval
The default setting is 105 seconds.
A global neighbor port is a Layer
2 aggregate interface that acts as
a neighbor port.
