Solved: 6VPE and Dual Stack Core?

sean_evershed · ‎11-20-2012

Hi,

I've been following this discussion on a MPLS migration to IPv6.

https://supportforums.cisco.com/thread/2181573

I have the following customer requirements:

- Dual stack IPv4/IPv6 across the entire network including the core.

- Run 6VPE between the PE routers

Is it true to say that this is not a supported configuration? 6VPE only runs on a native IPv4 core?

Thanks

Sean

6VPE is a tunneling technology to allow you to run IPv4 and IPv6 over an IPv4-only core and provide dual-stack at the customer edge. The customer is blissfully unaware that there is anything other than dual-stack - or better described as IPv4 and IPv6 capabilities - at their demarcation.

If you configure your entire core with dual-stack, there isn't really a need for 6VPE. What you will need is a solution for LDPv6 or what is sometimes referred to as MPLSv6 (http://blogs.cisco.com/tag/ldpv6/).

cheers.
