Authors, Sorry, I missed an important one when writing up my notes: Somewhere you should state that the LSPs signaled per the document must use Switching Type = WSON-LSC [WSON-OSPF] Encoding Type = Lambda [RFC3471] Label format = per [RFC6205] You should probably also state that this draft updates 5205 in that it permits use of the defined label type for WSON-LSC. This will need to be mentioned in both the abstract and in the body. Lou On 10/29/2013 2:28 PM, Lou Berger wrote: > Authors, > I have some comments on this document. Most are strictly > editorial.
