Re: [nvo3] [mpls] MPLS-RT review of draft-xu-mpls-in-udp-03

Historically there really was no MPLS enabled products that hit the right
price points and/or features needed for the DC -- but some of us operators
*have* implemented MPLS in the DC very successfully.  My observation is
that some vendors don't do MPLS/MPBGP very well and aggressively discourage
its adoption, while other vendors reserve them for their SP products for
which they  need reasons to charge a premium.  Now with support for MPLS in
merchant silicon, I don't see any good reason why MPLS-based DCVPN
solutions (IPVPN, E-VPN) should be held back, particularly if the overlay
tunnel is IP-based and MPLS labels are used for VPN context, split-horizon,
etc.
