It's a general question... perhaps basic!
RSVP-TE is one of the GMPLS protocol set.
Is it possible to use a GMPLS protocol outside an MPLS environnment?
e.g. RSVP-TE can be used to distribute VLAN in an Ethernet network.
If this Ethernet network has not an MPLS server network (i.e ETH > ETY, or ETH > SDH) is it still possible using RSVP-TE, that is a GMPLS protocol when there is no MPLS?
