[streaming] VLC on an IPv6 PIM SSM scenario

[Hansi]

Hello Sebastien,

Thank you for showing this to me. However, the issue that bugs me is that
upon specifying the (S,G) pair in VLC and pressing OK. Shouldn't it be that
the application will generate a MLDv2 Join Message to the upstream router
indicating that it wants to join the multicast group specifiied in the (S,G)
pair? Please correct me if I'm wrong.

Unfortunately, upon doing so. I dont see any MLDv2 Join Message. Though I
see Multicast Listener Report messages but not intended for the multicast
group specified in the (S,G) pair.

Appreciate you inputs on this.

Regards,
Hansi
