Oh, that's not the WORST of it.

IPv6 is coming. All gear needs to support it. Here are the basic models
of security from the router that we can use and pros and cons for each.
You do NOT want DSLAMs which enforce their own security.

Engineer: I disapprove of that DSLAM. It has IPv4 security measures you
can't disable (PPPoE and DHCP security! Wow!), doesn't support enough
q-in-q support to use an isolation model, and doesn't have IPv6 support
itself to make up for what it breaks.
Telco: Well, we're buying millions of dollars worth, so we'll just have
to make it work. Vendor says it'll be IPv6 ready later this year.
... 1 year later ....
Telco: Why did we do this? They say it will be ready later this year.
The problems we've had with this vendor have been awful. We should have
used someone else.
Engineer: No worries. I'm sure they'll get the support ready for you in
time. I'll have my side sitting here waiting on them or worst case
you'll spend some money to work around/replace them.
