Hello Everyone,

I support the draft; and I therefore implemented it on ExaBGP master.

I am will keep an eye on the discussion regarding the potential issue transiting messages with larger than 4k total attributes size could cause. 

I would have no objection myself on seeing an arbitrary limit on the Total Path Attribute set to prevent backward compatibility as the most likely quick win is going to be on packing more NLRI ATM.

That said, I am not aware of any guideline in previous RFC to cover this issue and it is already possible to encounter this problem today. So while the draft make the issue more likely, it does not make things worse from a specification POV.

I am therefore wondering if this should not be covered by another unrelated RFC as it can affect current speakers and is not specific to this draft.

Sincerely,

Thomas
