What is the current state/use of OSPF-TE?
Something you don't hear about much, for sure. Is this something that wasn't designed well, supported well, or was it just superseded by label based switching by the vast Telco market?
I assume you mean RFC 3630 "Traffic Engineering (TE) Extensions to OSPF Version 2"? This would be used by providers running MPLS, RSVP-TE and using OSPF as the IGP. As far as I can see it is supported by all major vendors. The reason you don't hear all that much about it is probably that a significant number of providers running MPLS and RSVP-TE use IS-IS as their IGP (we do).
