[c-nsp] Mixed PPPoA and RBE on 6400, with pvc ranges

[Robert Tarrall]

Here's the situation: we're a Qwest DSL host ISP moving from a
multiple-T1 setup on a Cisco 3620 to one DS-3 on a 6400.  We have mostly
PPPoA customers with a few bridged (RBE), one customer per PVC.

On the 3620, I've got a single multipoint interface for each T1 that
handles all the PPPoA customers; I have to manually list each PVC
(annoying) although using class-int means they can at least pick up a
default config.  Bridged customers each have their own point-to-point
interface.

On the 6400, I'd like to use pvc ranges ("range foo pvc 1/32 1/1032")
to avoid manually listing each PVC under the multipoint interface.
However, mixing in some bridged customers appears to break that trick.
I don't think we can mix RBE and PPPoA in the same range - correct?

Only alternative I can think of is to get Qwest to manually assign
bridged customers to PVCs outside the range we use for PPPoA - maybe
use a VPI of 1 for the PPPoA customers and a VPI of 2 for RBE folks.

Am I missing any better way of doing this?
