The WG Last Call for the subject document has completed. However, we are in the midst of some discussions as to whether or not we should attempt to satisfy some the Automatically Switched Optical Network (ASON) reqjuirements (Refer to draft-ietf-camp-gmpls-ason-routing-reqts-05.txt). I have some minor concerns with this. 1. While some of the ASON documents have gone through ccamp last calls, it still seems to me that the ink may be wet on the ASON requirements. 2. The proposed addition to OSPFv3 TE will satisfy the requirement to advertise TE information for multiple data plane elements (i.e., LSRs). However, there are other requirements (e.g., multi-level area hierachy) which are not satisfied. 3. This document is applicable to OSPFv3. However, we need a solution that applies to OSPFv2 as well. 4. If you accept #2, what about backward compatibiliy? Unknown TLV types are ignored so it would seem back compatible. However, this would have the undesirable side effect of associated TE information for all subordinate LSRs with the OSPF router. Hence, it seems at least one other new TLV will be required to advertise the new Router Address TLV for OSPFv2. #2 and #3 make me think we might be better off with a separate OSPF ASON document.
