We do this with an IPTv partner that use our network to send 
video to their customers.

We peer with them via BGP so that they learn the routes we 
assign to the STB's. We then also run PIM on the point-to-
point interface with them so we can learn Multicast 
information.

That said, we're not running regular PIM-based Multicast. 
We're doing Juniper's NG-MVPN infrastructure. But from an 
interconnect scenario with a different routing domain, it's 
the same.

Cheers,

Mark.
