PIM and IGMP Snooping Interaction
This section describes how to handle the scenario where IGMP snooping and PIM snooping are
both enabled for the same VPLS.
When both PIM snooping and IGMP snooping are enabled for a VPLS, multicast traffic is
forwarded based on the combined multicast forwarding table.
VPLS Multicast-Aware High Availability Features
The following features are HA capable:
• Configuration redundancy — All the VPLS multicast-aware configurations can be
synchronized to the standby CPM.
• Local snooping states as well as states distributed by LDP can be synchronized to the
standby CPM.
• Operational states can also be synchronized, for example, the operational state of PIM
proxy.
