IOS XR- Multicast

Hello,

i was practicing the Multicast lab from the INE workbook

i am using GNS3 with XR1 being Cisco-XRv and XR2 is a regular IOS

when simulating a sender from R8 and receiver from R7 it is not working

while it is working the other way around when the sender @ R7 and receiver @ R8

when the sender is R8 and there is a receiver @ R7, the (S,G) doesn't reach Xr1

i am sure from the config since it i working when reversing the roles

is it a bug with XR ??

Thanks

 

 

 

R8:sending pings with no receiver
