Hi all,
By default, PIM join messages are sent toward a source based on the RPF routing table check. If there is more than one equal-cost path toward the source, then one upstream interface is chosen to send the join message and add to the multicast data tree. This interface is also used for all downstream traffic, so even though there are alternatives interfaces available, the multicast load is concentrated on one upstream interface and router.
In cisco IOS, For PIM sparse mode, is it possible configure PIM join load balancing to spread join messages and traffic across equal-cost upstream paths (interfaces and routers) provided by unicast routing towards a source?
Many thanks in advance for your support
