2 pppoe server for 2 class of clients

hi, I have one radius server and I have two class of clients.
I want to set up two pppoe servers. How can I authenticate first class of clients with server #1 and the second class of clients with the other server?

I think using in first " PPP client configuration" and " PPP server configuration"
----------> service-name=service1

and in other " PPP client configuration" and " PPP server configuration"
----------> service-name=service2

…it’s right??

--------best regards

you have to configure two ppp-profile, one for server #1 and one for server #2, after you have to specify the interface where running server #1 and the other one where running server #2 on pppoe-server configuration.
