All:

I noticed that when I created a VRF on a 6500 running 12.2(33)SXH6, it created another interface:

#sho vrf ipv4 interfaces
Interface                        VRF                            Protocol   Address                                        
Vlan916                          VRFNAME                        up         x.x.x.162                                 
VRF_1_vlan1020                   VRFNAME                        up         x.x.x.162

We are using "vrf definitions"

vrf definition VRFNAME
 rd x.x.x.x:914
 !
 address-family ipv4
 route-target export asn:914
 route-target import asn:914
 route-target import asn:902
 exit-address-family

I cannot do a "show int VRF_1_vlan1020" on this mysterious interface. Any one have an idea why it was created?

Thanks for any insight.
