Configuring a virtual routing and forwarding instance (VRF) for IPv6 is no different from configuring a VRF for IPv4. A VRF is an address family-independent object that can be enabled and configured for each of the supported address families. Configuring a VRF consists of three steps:

1. Configuring the address-family-independent part of the VRF

2. Enabling and configuring IPv4 for the VRF

3. Enabling and configuring IPv6 for the VRF

First, a VRF is given a name and a route distinguisher (RD). The RD is configured outside the context of the address family, although the RD is used to distinguish overlapping addresses within the context of a particular BGP address family. Having separate RDs for IPv4 VPN addresses and IPv6 VPN addresses does not matter. On Cisco routers, the RDs are the same in order to simplify configuration and VPN management.

Users can configure policies in common between IPv4 and IPv6 when outside any address-family context. This feature is shared route targets (import and export), and it is useful in a migration scenario, where IPv4 policies already are configured and IPv6 policies should be the same as the IPv4 policies

As of 12.2(33)SXH, 6VPE is not supported on the 6500.

6PE deployment is pretty straightforward. You just need to have either a sup720 or sup32 in your 6500 in order to support it.

Hope this helps,
