Yakov:

How does accepting of Morin's draft improve the profitability of the
current VPN/mVPN service?

On the subject of "we definitely do not want to tweak", I'd like to
remind you that during the early days of 2547 VPNs some of its opponents
were saying that they are against 2547 VPNs because they do not want to
"tweak" such a crucial protocol as BGP to carry VPNv4 routes.

Today AT&T has "2 million VPNv4 routes in the US alone" all carried in
BGP, and a successful 2547 VPN service. None of this would be possible
if we would not tweak BGP.

Yakov.
