ADSL PPPOA mode.

Hi,

maybe there are different way of doing the same things with IOS 12.3. In particular I wondered about PPPOA mode for an ADSL connections.

I searched for very basic configuration of PPPOA, PPPOE and RFC 1483 modes. I thought that for PPPOA the following conf was good and the only possible in ATM0 interface:

pvc 8/35 encapsulation aal5mux ppp dialer dialer pool-member 1

but a guy working with me tried the following

pvc 8/35 dialer pool-member 1 protocol ppp dialer

without specifying the encapsulation mode. Is "aal5mux" perhaps the default value for IOS 12.4?

Thanks,

Alex.
