Multicast on Cisco XR(outgoing interface list is empty)
I am new to multicast. And I have configured the Cisco XR router with a multicast configuration. Cisco XR is connected with a multicast receiver. and I see the following entries on Cisco XR.
There are (*,G) and (S,G) entries. (*, G)'s RPF points to Gi0/0/0/5. 18.104.22.168 is the upstream router in (*, G) tree. (S,G)'s RPF points to Gi0/0/0/1. 22.214.171.124 is the upstream router in (S, G) tree.

No interfaces in immediate olist
The receiver is receiving the traffic. But why do SPTs outgoing interface show 'No interfaces in immediate olist'? RA flag is also set on the (S,G) entry that means the traffic is flowing through the SPT. I am not able to understand this behavior of not showing any outgoing interface but traffic is still flowing through SPT.
