Channelized ATM DS3?

[jimb]

We have an ATM DS3 circuit terminating on a Cisco 7204 delivering 45mbps. Is it possible to configure a router to forward some of the data from that circuit to be processed by another router depending on the PVC? I want to split DSL subscribers into two differint Class C addresses depending on the customer, and I am looking for a way to do it without having to buy another ATM cicuit.

Sounds like you want the same switching facility as the routers provide for a frame relay connection.

Unfortunatly you cannot switch the VC at L2 across to another interface, although when I asked about this I was told it is possible with an ATM switch such as a 1010.

Have you thought about doing this using a route map, match all incoming traffic on that VC and set the next hop as either another sub interface or an IP address?

Hi Andy,

I don't think a route map will help. I need to split my subscribers into two subnets... one group that will be filtered for content, and another that will be unfiltered. Worse yet, I have to authenticate each group to a differint RADIUS server. I have one group using VPDN and getting IP addresses from a dialer pool, but I can only define one dialer pool per VPDN using PPPOE, and only one VPDN per router. That leaves DHCP for the other group as one possible way to assign the unique subnet to that group, but how to authenticate them?
