AS1273 / Cable & Wireless runs an excellent IPv6 (native) network with
extensive set of BGP communities. Not a single v6 backbone I ever know of
even offer this level of service to their customers to date (Verio probably
does too, but I'm not very familiar with their v6 service yet). CW is
present at London too.

My experience in different European countries has been very good with:

- C&W
- Global Crossing
- Open Transit
- Telecom Italia (Sparkle/Nautilius)
- Teleglobe
- Telia Sonera
- TIWS (Telefonica International Wholesales)

(pure alphabetic order so no preference shown here, and I hope I don't
forgot anyone)

But you need to check local availability/pricing in each case for native or
tunneled service, which may depend on the PoP/interface type. I'm not sure
if BT offers already a commercial service or is only available through UK6X
(which proven to be very good also).

Here also about Level3, but not tried myself (will be happy to have some
feedback).

I have got very good comments also from NTT/Verio.

Jordi

Jordi,

how many kilometres above earth is that view from? How much
applicable is that to a small port in London? Your mail

Hi Alexander,

I know all this people is present in London, so the number of kilometers
should be really short ;-)

I think I must say, next time, I've no special commercial relation with any
of those, neither will get commissions or anything like that. Was only
trying to make a summary of my knowledge of what is available, not a
marketing speech.

I didn't included Tiscali in the list, because it was clear that it was
already an available choice.

Regards,
Jordi

Jordi, All,

since this comes up and is interesting also for me:
In what way / how far are these networks offering native
IPv6 'not just in the core' or 'on most routers', but
especially in all POPs, even those only for customer
aggregation?

FT/Opentransit - not sure, mostly native if not all native by now
C+W - AS 1273 is native, not sure how much of in- country UK they cover
NTT/Verio - known thing, all native
Teleglobe - unsure, mostly native
Telecom Italia Sparkle - unsure, native... (somehow[tm])
Telefonica - unsure, native... (somehow[tm])
Sprint - tunnels for the desperate with full routes or nothing (argh)
Global Crossing - mostly tunnels
Telia - last I know is using tunnels
Level3 - unsure, but started offering IPv6, too early to say I think

Who else? 12702 exists, but had some E1 circuits two years
ago between their nodes in UK/NL/DE... *cough*

There might be several local networks, sure, but I am
thinking more of the European backbones.

I will leave out my employer's network, and did not intend
my previous mail to be picking on that aspect.

Does anyone want to comment? I can and will summarise if you
send things to me. Might save on spam^Wmails...

I understand that they are currently moving to a native setup.

Currently being tested by some customers, they say that tunneled service
will be available very soon to all customers and it will become native
"later this year".

We are dealing with what I call a bug and cisco calls a feature
request, hence the partial view. I hope to solve it one way or the
other when I come back from vacations.

Can you share details? Perhaps that prevents others in running into the
same problem...

Hi Jordi,

"very good" aka "does IPv6 at all"? For example

> - Teleglobe

I can currently not vouch for Teleglobe. They do IPv6 (in some places
where you are lucky even 6PE (~= native)), but have been unable to
provide a full routeset since almost a year

2001:5A0:701:1::1
4 6453 18631 8165 3103 0 0 1d21h 544
2001:A60:0:201::1:1
4 8767 6944 5446 3103 0 0 1d21h 606

both sessions are well filtered (no more specifics), so those are really
missing aggregates. For example almost all routes of european NRENs are
missing now for months (all that have only GEANT transit but none on
their own). And the most-taken way out of their network (besides some
peering in Amsterdam and Paris) is transatlantic through Viagenie, which
has most paths through Sprint and HE.net. Not the greatest connectivity
there.

> - Telia Sonera

Telia is mostly tunneled inside as far as I know and seems to have no
sane upstreams, and quite bad paths overall (check for 2001:2000::/20 in
grh.sixxs.net).

For the records, I've been so far very happy with my (Munich-only)
upstream M"net, which is itself mostly buying from Cable&Wireless (which
is a very good option for global IPv6 transit). They also have some GBLX
(currently tunneled) who are currently going to native deployment and do
have quite a reach themselves (no problems with them, too). Maybe you
get even more when you buy at some local supplier in London which
itselfs buys transit from sane global parties.

Global Crossing can provide native access at IP POPs today. This
includes the initial request of London.

Subject: London, UK IPv6 transit recommendations

Does anyone have any recommendations for IPv6 transit providers who can
offer service in London? We're currently hooked up to Tiscali and very
happy with them, but want a second provider for redundancy; we have some
peerings that help, but really want someone with a native network
themselves.

NTT/Verio I'm aware of; anyone using them or aware of other options?

(Happy to hear sales pitches off list, provided they're plain text
email.)

Relevant bug is CSCsb02664: in an MPLS/6PE setup, packets coming from
the MPLS cloud are not switched to an ipv6ip tunnel (and viceversa).
Traffic local to the router works regularly, hence BGP sessions go up
but your valued ipv6 packets get lost.
I'm with 12.0.(26)S6 and waiting for cisco to tell me in which version
they will include
this "feature", i.e. correctly passing the packets to/from ipv6ip tunnels.
My workaround will consist in terminating all those peerings that are
over a short tunnel
(those peerings that are not native because the partners's IPv6 router
is not the same
as the one where we have the PNI) on a 7200 which is not affected by
this bug, but
being located in Italy will make all the US peerings suboptimal.

Oh, of course all of this is on 12xxx routers.

Anther missing feature is that etherchannel doesn't support IPv6, thus limiting
the IXPs where we can pick up some peerings. Not related to the above.
