Yes Marc, but if they are optional... some will be mandatory. What will be mandatory for Ipv4 Mpls backbone ? ;) If we use as mandatory dual stack the ipv6 vpn mpls not work. We must use 6VPE that is over ipv4. Today as you know LDPv6 is under developement by ietf and vendors will wait 1-2 years to deploy the protocol inside os. I think today and when ipv4 addresses will finsh the ipv4 mpls backbones remains the same ($$) and the 6PE and 6VPE will be used. Isacco Marc Blanchet ha scritto:

Hi Marc, your issue is true about IPv4 only backbone....but today for ISP with MPLS backbone the 6PE and 6VPE are used to deploy ipv6 on MPLS backbone.
I know (and have been helping providers to deploy 6PE and 6VPE). My point is to make it "mandatory" is the issue.

6VPE (RFC 4659) 6PE (RFC 4798)
These RFC are related to MPLS environment so I think 6PE and 6VPE should be mandatory for ISP that are using MPLS and offer ipv6 for direct internet connections and 6VPE for ipv6 over vpn mpls services.
So, the correct wording inside mandatory section would be:
- if IPv6 over MPLS and IPv6 over VPN MPLS features are requested, 6PE or 6VPE must be supported [RFC4798, RFC4659] The contracting authority shall specify the required protocol.
does not make sense to me.
6PE and 6VPE are two ways to run IPv6 over MPLS network, but are not the only ones. Therefore, it can not be mandatory.
Marc.
Is this acceptable?
Thnx, Jan Zorz
