[mpls-linux-general] IPv6 status with MPLS-Linux

[<ia...@g7...>]

Hi All,

I was wondering what the current state of IPv6 support was within
MPLS-Linux.

I browsed thru the archives, and noticed about a year ago a thread
between Vino Thomas, and James R. Leu, discussing the current state,
and James stated:

Did this ever get done ? Has there been any further work on IPv6
support since ?

(I'm not sure, but I think that was in reference using mpls tunnel)


I am (re)implementing my home network, using IPv6 natively, with
part of it shown below:

                                    (IPv6/IP) tun1|   |tun0 (IPv6/IP)
                                                  |   |
          columbia                                c2620
             |eth0(BGP 64512)                       |eth0(BGP 64512)
|------------------------------------------------------------------| BGP 64512
                                  |eth0(BGP 64512)
                             pathfinder
              (BGP 65097)tap0|        |tap1(BGP 65097)
                             |        |
              (BGP 65097)eth0|        |eth0(BGP 65097)
                           iiigw1   iiigw2
        (OSPF 0.0.0.97)eth1|             |eth1(OSPF 0.0.0.97)
                           |             |
                           |             |
                           +----HOSTS----+
            (OSPF 0.0.0.97)eth0   |  eth1(OSPD 0.0.0.97)
                                  |
                                  |dummy0

(Actually, all the routers/hosts that are shown "below" pathfinder,
are actually user-mode-linux instances, but they have connectivity
as shown, and partake in BGP or OSPF like any 'real' machine, using
zebra - As yes, OSPF is giving grief at the moment :>)

Remembering that my native transport is IPv6 (So assume no IPv4
- There is IPv4, but not a lot of it :>) how capable is MPLS-Linux ?
What needs to be done before I can run MPLS over IPv6 natively ?
