Hi, I don't see any TLVs defined for performing the on-demand CV operation on MPLS -TP Sections. Is this intentional? and Co-routed bidirectional tunnel identifier: A1-{Global_ID::Node_ID::Tunnel_Num}::Z9-{Global_ID:: Node_ID::Tunnel_Num}::LSP_Num Associated bidirectional tunnel identifier: A1-{Global_ID::Node_ID::Tunnel_Num::LSP_Num}:: Z9-{Global_ID::Node_ID::Tunnel_Num::LSP_Num} How does Static LSP Sub-TLV address the need of two LSP_Nums of associated bidirectional tunnel? Am I missing something? Thanks, Venkat.

Seems that there should be "On-demand LSP Route Tracing with IP encapsulation, over ACH" accordingly. What's reason behind this?
