Hi again,
One more point below:
Oct. 22, 2015 - Peter Psenak:
The TE Opaque LSA would be, presumably, required if SPRING is supported
which has no implications on whether RSVP-TE is enabled.
SPRING does not use TE Opaque LSA.
[JM] Just a quote from draft-ietf-spring-segment-routing:
"The list of segments can be specified explicitly or implicitly via a
set of abstract constraints (latency, affinity, SRLG, ...). In the
latter case, a constraint-based path computation is used to determine
the list of segments associated with the tunnel. The computation can be
local or delegated to a PCE server."
Though, in the Routing area, "constraint-based path computation" and
"affinity, SRLG" usually rely on TE/GMPLS opaque LSAs, you may advocate
this is only implicit... However, when it comes to PCE, the references
to RFC 3630 and 4203 extensions are explicit.
Regards,
Julien
