IPv6 PIM support for VPNs

To support IPv6 PIM for VPNs, a multicast router that runs IPv6 PIM maintains an independent set of
IPv6 PIM neighbor table, IPv6 multicast routing table, BSR information, and RP-set information for
each VPN.
After receiving an IPv6 multicast data packet, the multicast router checks which VPN the IPv6 data
packet belongs to. Then, the router forwards the IPv6 packet according to the IPv6 multicast routing
table for that VPN or creates an IPv6 multicast routing entry for that VPN.

Configuring IPv6 PIM-DM
This section describes how to configure IPv6 PIM-DM.
A receiver joins an IPv6
multicast group G.
Is G in the SSM
group range?
Is IPv6 BIDIR-PIM enabled?
Does G have an IPv6
BIDIR-PIM RP?
IPv6 BIDIR-PIM runs for G.
315
Yes
Is an IPv6 multicast
source specified?
No
IPv6 PIM-SSM runs for G.
