Re: [Isis-wg] WG Adoption Call for draft-xu-isis-encapsulation-cap

Please can people explain how

https://datatracker.ietf.org/doc/draft-xu-isis-encapsulation-cap/

might fit in with, or cause problems with this

https://tools.ietf.org/html/draft-ietf-isis-auto-encap-03

which was adopted by the ITU-T and appears to be still very much part of 
IT-T G.7712.
The PDF of that document is available here

https://www.itu.int/rec/T-REC-G.7712-201009-I/en

and you probably want to go to page 46.

or it is defining something entirely different?

The ITU-T version defines an "Encapsulation capability TLV" with code 16 
decimal, whereas draft-xu-isis-encapsulation-cap says "routers 
advertises their supported encapsulation type(s) by advertising a new 
sub-TLV of the IS-IS Router CAPABILITY TLV"

is it dangerous to have two mechanisms to advertise the same thing?

also it seems a shame when TLV 16 is already defined as using subTLVs 
and so could easily be used for the new purposes that 
xu-isis-encapsulation-cap suggests.

Apologies if I have misunderstood something; I have been away from this 
for a long time.

regards, Philip Christian
