Aijun -
Since advertising some sort of capability would also be unusable until all routers were upgraded to understand the new capability advertisement this does not help. 😊 The consequences of enabling a form of authentication which is not supported by all nodes is an inconsistent LSPDB - which means protocol function is broken. I would also point out that the incompatibilities are discussed in the original specifications (RFC 5304 and RFC 6232) - both of which have been published for a number of years. The points being made in this regard in this draft aren't new.
