Hi Chris,

I've been following that thread šŸ˜Š

IMHO it would depend on the nature of extension and seems not something that I would speculate about.

Thanks,
Ketan

> [KT] The behaviors currently listed in the draft do not have an argument nor is the use of B and N required for them. We cannot preclude a future use-case or extension where such behaviors introduced are also applicable to ISIS. So IMHO ruling such aspects out might not be the right thing to do from a protocol extensibility perspective.

No opinion here on this sub-sub-TLV; however, it has been stated elsewhere that this document will be re-spun for each new behavior that is to be carried in IS-IS (not my personal preference, fwiw...).

Thanks,
Chris.
