Mani,
The L bit processing would be no different from the normal processing in
other subobjects. The ingress IP address in the LSP subobject is the address
of consideration in this subobject.Anyway, to make it clear and explicit it
can be incorporated in subsequent revisions.

Regarding the sending of path message through the tunnel, I think this is
more of an implementation issue. The ingress of the tunnel, which processes
the LSP subobject, would identify that the path message should be
transparently sent to the egress without creating path state in intermediate
nodes.The tunnel which is like an IP interface, would be the outgoing
interface for reaching the egress. I would add an explicit mention of this
in subsequent revisions of the draft.

Thanks and Regards,
Vijay

The ERO processing for the LSP subject needs clarification. Can this
be added in your draft, how to process the ERO object in case of Strict
ERO, Loose ERO etc.,

Can this be explained as well. I am not sure to which FEC, this path
message (data) will be mapped to?

Because the initial tunnel/LSP is created for a specific FEC.
Can this be added in your draft?
