You'll have to be using ethernet mode though - PPPoA to PPPoE translation likes to mess things up a bit from experience.

With this, what would be the chances of having a Draytek Vigor 120 working using its PPPoA-PPPoE bridging, and running pppoeclient on another system?

So it seems like i'm getting a different response here than the guy from support@snap.

Maybe you guys could look at that. I'm fine with being told "No and here's why and here's what we might be doing in the future" but instead the support guy shifted the blame to telecom..

Hmm, while pulling 15mbit over IPv6:

I wouldn't have expected more than about 10 - 11 meg on a tunnel on an 877. I don't think the tunnels get much if any hardware acceleration. (I am assuming you are terminating your SIXXS tunnel on the Cisco)

Nope, no tunnel, this is native v6.

Do you have 'ipv6 cef' in your config?

Not sure sorry - I'll post some stats later in the week to compare by. Can you send me a show ver?

If you want to just setup a simple 6to4 tunnel, then there is a 6to4 anycast server close to Snap (which appears to be run by FX Networks).

This could be one of Nathan Wards teredo boxes which alot of service providers are hosting. I believe he may have one in Snap's network but I think he manages these. Regardless teredo isn't a nice solution and probably shouldn't be relied upon.

It is one of Nathan's boxes at FX and Snap does have one but It looks like the BGP side needs someone in know to have a look, either that or the box is offline.

jbergler:

The other thing I have noticed is that the Cisco 877 is hitting a CPU limitation of around 11Mbps for IPv4 and I think it is worse for IPv6 (IOS 15.1, ZBFW, PPPoE, NAT). What happens for people that want full ADSL2+ speeds? What Cisco router will handle VDSL2 speeds without breaking the bank?

Theres an 877 software bug (fixed by 12.24 i think) which limits dsl to about 16meg on PPPoA.
I've seen pretty poor performance on the 877's running PPPoE using the 0/110 pvc but its a new feature so I imagine this might get better with newer code / hardware.

As with other cisco kit the more features you enable the slower it will perform.

We've played with the 887VA's a bit and they seem to fly.

I agree with Jonas, I don't expect you'll get much more from an 877. Although judging from my 1841 at home, it's the IPv6 ACL's that kill the performance. The 887V series start at about $587 retail.

jbergler: We are working on a V6 DSL offering and hopefully we should be able to begin trialling publicly within 6 - 8 weeks, ...

Is the timeline for IPv6 on track with the previous expectation? Can you start to offer trials to customers? Do you have any new information? Is contacting the support team a viable way forward? Thanks.

Any word on getting static V6 prefixes yet? (alleged) Data cap upgrades are making it verrrry tempting to switch!

I don't think there is, except I have noticed that my IPv6 prefix never changes (Static home IP)

I've been told they're "coming soon"

From support email on the 3rd of Feb:

Static IPv6 allocations are coming - they are on our IPv6 deployment schedule, but at this stage approximately 2 months away from being possible.

We have a number of systems that need to be updated (RADIUS to name one) - once this is done, we will be able to statically assign IPv6 prefixes.
