Hi Parth,
RPF will pass but not for both links. By default, the RPF check will be done for the neighbor with the highest IP address. This means that by default, ECMP multicast load balancing is disabled.
For example, let’s say there are two routers…R1 and R2. Between R1 and R2 we use two interfaces. These interfaces have the same metric in whatever IGP we are using. Let’s say R1 has IP address 192.168.12.1 and 192.168.21.1 on these interfaces.
R2 will then send the PIM join to the highest IP address PIM neighbor, 192.168.21.1. That’s the interface that will be used to receive multicast traffic.
