L3 mpls vpn multicast issue on ios xr

Hello lads,
Having a problem with multicast inside a L3 MPLS VPN on IOS XR. We have a mix of XR and IOS PEs. In MPLS core I can join Lo interface to a group on any router and then ping it from any other router. Mfib and mrib on XR have both (*,G) and (S,G). Same good on IOS.

Setup features a single static RP for now on one of XR routers.

Inside VPN all PEs see each other as PIM neighbors via MDT tunnels. MDT groups are configured with default 232/8 SSM range. Default MDT group is 232.0.0.1 and data MDT groups are 232.0.x.0/24 where x is unique per site.

Each PE has Lo10 in this VRF with PIM SM enabled and test MC group joined. MP BGP has mdt family activated on both RRs and RR clients.

From RP and IOS routers when I ping that MC group inside VRF only IOS routers reply, no (S,G) appears on on XR, but happily appears on IOS routers. Seems like mdt tunnels terminated on XR are not well.

I went through INE SPv3 WB example for multicast VPN but they use BSR as opposed to static RP in my case.

Any suggestions? I'll provide relevant config sections tomorrow, don't have them handy now. :-)
Sorry for rather long-winded write-up.

TIA
Alexei
