Rakesh, authors, I have not been thinking about this too much. But if you look at fig 2 of draft-cheng-spring-mpls-path-segment, and you need a GACh between A and D, I'd say that the GAL will be at the bottom of stack. What if you need the CACh for the sub-path B to C, where will the GAL go?

Greg, We are close, though I hope the rules are that GAL is bottom of stack, and that a packet with a GACh does not carry user payload. I should have said that "if you want a GACg for the I don't understand why we need a "new" SR tunnel, the GAL/GACh can ride with the GAL as bottom of stack

Hi Loa, another tunnel with the Path segment from node C is, in my view, very close to SPME tunnel. The Path segment from C is needed because Path segment from D is not known to the node C, cannot be associated with the right SR-tunnel segment, i.e., tunnel B-C. The fate sharing may be achieved by
