Cisco ATM - Bridge1483 PVC's

[rainman]

Hello,

I am trying to terminate a bunch of ATM VCC's to a Cisco router. After some research it seems my end devices only support bridge1483 PVC's and not routed1483.

What is the best method for terminating a large amount of VCC's to an ATM interface on a Cisco router? The example the manufacturer provided for the end-device involved an ATM type of "point to point" however I am planning to manage these PVC's as "multipoint" and keep all them on the same IP subnet (/24).

I believe I can accomplish this with Integrated Routing & Bridging (IRB) using BVI interfaces.

Has anybody done this before and if so what is the preferred method? I have bridge groups running on other devices however I want to make sure this is the best way to do this so I do not have to change my configuration later on.


Any thoughts?


Thanks,

Rainman

Everything I've read on Cisco's site spoke of doing it with bridge groups. I'd be curious to know if somebody is doing it differently.

All,

The IRB solution did work and I am able to reach my end devices (Calix C7 BLC).

Here is my working configuration in case someone else needs to do this same setup because in Calix's documentation they only provide a P2P example but this gets hairy when you have many devices to manage. BVI works rather well.
