Actually, there is no such thing as "straight IP" - you always use some sort of data link layer. In this case, it could be PPP, HDLC, LAPB and probably frame relay (I am not sure when frame relay can be used). HDLC is usually a better choice than PPP. LAPB is used for X.25 networks. -- U U M M M M Szymon Sokol -- Network Manager U U MM MM MM MM University of Mining and Metallurgy, Computer Center U U M M M M M M M M ave.
