Re: [Lsr] Working Group Last Call for "OSPF Link Traffic Engineering (TE) Attribute Reuse" - draft-ietf-ospf-te-link-attr-reuse-07.txt

Speaking as WG member... 

Right, there was a protracted WG discussion. IIRC, Olivier was opposed based on some code he had written for quagga using OSPF TE LSAs for purposes other than traditional RSVP TE. At the end of this discussion, we reached WG consensus with the understanding that some code would need to change. 

Thanks,
Acee

    There’s has been significant amount of discussions on the topic some time ago, mostly with Chris Bowers. Please take a look, should provide more context.
