Well they have been redback for a while.
For the DSL network. The gateways to the backbones are still cisco 6400s.
Verizon services are currently on a PPPoE vlan.
No more static, but may be offered in the future.
The redbacks arnt the reason for slowdowns.
They actually are performing as well as the old ciscos.
Its the backbones that are like over capacity.
