Multiple routing tables

Dear Sirs,

I would like to know if IOS is capable of using several separate routing tables, automatically associated (maybe using ACLs, calling ID, calling number, etc.) with the relevant "customer ID". The issue naturally appears when implementing telco class access servers with PRI links, and each incoming call needs to be treated according to the settings of its class. For instance, such an access server should route each call to a different RADIUS server for authentication, or each caller should use a certain addressing plan, maybe conflicting with other addresses from another customer. Here, the customers could be ISPs that get dial-up bulk services from the telco access server, or large enterprises, and the telco avoids imposing addresses to the customers.

In a larger context, if we want to service leased-line access, is there any solution (apart from MPLS) to this problem?
