PIM support for VPNs

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

group range?
Is BIDIR-PIM enabled?
Does G have a
BIDIR-PIM RP?
BIDIR-PIM runs for G.
107
Yes
Is a multicast source
specified?
No
PIM-SSM runs for G.
