Controlling PIM resources for multicast VPNs

Junos OS introduces the following PIM configuration options to protect against potential misbehaving customer edge (CE) devices and VPN routing and forwarding (VRF) routing instances:

•  Limit the number of accepted PIM joins for any-source groups (*,G) and source-specific (S,G) groups.
•  Limit the number of received PIM register messages on a rendezvous point (RP).
•  Limit the number of group-to-RP mappings on an RP.
