Multicast - IGMP Static Joins

[supunit21]

Hi All,

We have a PIM domain that is running PIM-SPARSE mode and it's working fine. 

We have a customer who needs our multicast feeds. But we cannot allow PIM neighborships between us and the customer.

So we decided to enable IGMP Static Join on the customer-facing interface. 

After configuring static join, we can see that the customer-facing interface in the OIL and disseminating feeds towards the customer. 

What configurations should be enabled on the customer side router? Does it accept multicast feeds without enabling any additional configurations at all?

Hello @supunit21 ,

the customer router needs to be configured for IP multicast routing.

ip multicast-routing

ip pim sparse-dense mode on each interface

In addition to this the customer router needs to have unicast routes covering the source addresses of all the streams and pointing to the interface receiving the mcast streams to pass the multicast RPF Check that is performed on the source address.

Hope to help
