MPLS and multicast

[mradchenko]

I'm trying to set up multicast routing using pim sparse mode across an MPLS line (with BGP routing).  I've set up an RP at the main site on the core switch and sening rp announcement (ip pim send-rp-announce).  It's working fine at the local site and all the remote sites that are connected with L2/L3 MAN links but it's not working to any sites that are connected with an MPLS line, not even if I set up a static RP on the remote routers.  Is there any special configs I need to set up on those MPLS connected remote sites? 

All those sies get the required routes with BGP, so they can see the RP IP and all the servers that send/receive multicast traffic.

Thanks!

You need to consult your MPLS provider if you want to natively have multicast via the MPLS backbone.

Your other option is creating GRE tunnels to transport the multicast but this can be messy and defeats the purpose of having MPLS in the first place.

Yea I'm trying to avoid going the GRE tunnel route...thanks, guess I'm calling the provider.
