Re: [Idr] WG adoption call for draft-abraitis-bgp-version-capability-08, to end September 25

[Robert Raszuk <[e-mail]>]

John,

Just to clarify one important point. I am not stating that this extension
will break BGP today.

However I am stating that Tragedy of Commons is not an imaginary paradigm
but real danger. It is not this extension which I would be afraid of to add
into BGP capabilities. It is the number of extensions like this one
acting together (which IDR may never observe if we take extension by
extension approach) which may lead to making the Internet weaker.

Any way I am not against this add on - in fact I think it has some limited
use case (like described by author to find which LXCs demons are talking
from compute to my BGP TOR), but let's just please package it nicely.

For example would putting this in large community along with lXC next hop
as a prefix would not be sufficient ? Sounds pretty harmless to me yet will
serve the intended purpose.

Best,
R.
