Routers and frames

Hi
It may seem odd but has anyone got definitive information on routers using frames to communicate? I know they use frames for the local LAN segment but the Sybex book states that they use frames too?
Any help to clear this up appreciated.
Thanks.

I used to be undecided but now I'm not so sure.

It depends on the technology and what layer the transmission is taking place. Frame-relay is a frame switching technology that is used on Cisco routers for example.
Also when data comes into the router, the frame is stripped and the packet is processed. But when it gets transmitted again, it is reframed with another layer 2 frame. Layer 2 will keep changing hop for hop but the packet will never change.There is no place like 127.0.0.1 BUT 209.62.5.3 is my 127.0.0.1 away from 127.0.0.1! -

How the Layer 3 packet is encapsulated depends very much upon what layer 2 protocol is in use.More systems have been wiped out by admins than any cracker could do in a lifetime.
