With LSP ping, you would ping the first LSP until the second is set
up. Once that is complete you can start pinging it as well. You can
even wait for a successful reply before ceasing pinging the first and
tearing it down. (Though I think that's probably overkill.) So you
don't have a gap, you actually have an overlap.
With Y.1711 I don't understand how you would map an RSVP tunnel/lsp-id
to a TTSI. There are just enough bits to fit both RSVP fields into
the TTSI LSP-ID, but that doesn't leave anying for LDP, BGP, etc.
Maybe you can enlighten us.
