so some extent it depends on exactly how far 'down' into your DC you extend MPLS VPNs.

for example, do you extend it down to the access layer?
or at what point do you map a MPLS VPN into a VRF or VLAN?

because even without MPLS today, many folks with N7K quite happily make use of VRFs on N7K, although in cisco parlance you'd call it "vrf lite".

one nice characteristic of NX-OS is that everything is vrf aware.  i.e. there is no such thing as a "global table", rather there is a "default vrf" where everything goes if you don't explicitly use vrfs.

SOME people use it for L2.  the majority of deployments i've seen are making extensive use of L3.
