...when we're starting to deploy yet another IPv6-only technology :)
Hello all,
as a fairly large ISP (for Greek standards at least), we've been
affected by IPv4 exhaustion for quite some time now. A few years back we
gave LW4o6 a go, as documented here
https://ripe76.ripe.net/presentations/11-lw4o6-deployment-as6799.pdf .
In the end, it did not work out very well. Quoting myself (from v6ops
mailing list), the reasons behind that were:
"In no particular order:
1. CPE (almost OK after ~2 years and god knows how many iterations)
2. lwaftr performance (worth noting the the lwaftr is implemented as a VNF
3. vendor's reluctance to continue (much needed) dev/ment because of
*lack of interest from other ISPs* "
Please take extra note of (3).
In any case, being the optimists we are, and having supportive mgmt, we
decided (once more) against burying ourselves deeper into CGN. This time
we're going with MAP-E (which incidentally was our first choice), mainly
because we understand it and our MAP BR vendor does too :) .
So, as I already mentioned, we're just about to deploy it commercially.
We've tested with 2 CPE vendors sucessfully and we're just ironing out
some provisioning details before launching. Deployment will be gradual
of course and very very cautious.
Unofficially, we are aware of a couple of similar trials from other ISPs
and we'd love to hear about people who have already deployed such
technologies (IPv6-only with IPv4aas) or are thinking about doing so.
After all, that is exactly what this WG is about :)
thanks for reading,
Yannis
