Hi All, When RSVP-P2MP tunneling is used as P-Tunnel protocol, then how can a shared C-tree be used or that shared C-tree can be used only when P-Tunnel protocol instantiates MI-PMSI through PIM or mLDP? If a shared C-tree is used rooted at C-RP on some PE router for a mVPN, then do all PE C-PIM instances send C-Register and C-Join/Prune PIM messages directly to the C-RP via P-Tunnel (P2MP-RSVP tunnel) with destination address set to the C-RP Address? The draft does not clearly say anything about sending such C-PIM packets over the provider backbone. Greatly appreciate any help/hints on these topics. -- thanks, Rohan Sen
