Load-balancing PIM join messages on multicast VPNs

Junos OS now supports customer PIM (C-PIM) join messages to be load-balanced across unequal EBGP and IBGP paths in a Draft Rosen MVPN and a next-generation MVPN in the following ways: In the case of a Draft-Rosen MVPN, unequal EBGP and IBGP paths are utilized. In the case of next-generation MVPN: Available IBGP paths are utilized when no EBGP path is present and Available EBGP paths are utilized when both EBGP and IBGP paths are present. This feature is applicable to IPv4 C-PIM join messages over the Layer 3 MVPN service.
