During PIM Neighbor change/UP event, pim_scan_oil api scans all channel oil to see any rpf impacted. Instead of passing current upstream's RPF it passes current RPF as 0 and does query to rib for nexhtop (without ECMP/Rebalance). This creates inconsist RPF between Upstream and Channel oil. In Channel Oil keep backward pointer to upstream DB and fetch up's RPF and passed to channel_oil scan. Decrement channel_oil ref_count in upstream_del when decrementing up ref_count and it is not the last. Created ECMP based FIB lookup API. Testing Done: Performed following testing on tester setup: 5 x LHR, 4 x MSDP Spines, 6 Sources each sending to 1023 groups from one of the spines. Total send rate 8Mpps. Test that caused problems was to reboot every device at the same time. After fix performed 5 iterations of reboot devices and show no sign of the problem.

INTRODUCTION
qpimd aims to implement a PIM (Protocol Independent Multicast)
daemon for the FRR Routing Suite.
qpimd implements PIM-SM (Sparse Mode) of RFC 4601.
Additionally MSDP has been implemented.
In order to deliver end-to-end multicast routing control
plane, qpimd includes the router-side of IGMPv[2|3] (RFC 3376).
