Converting from Frame-relay to ATM. Traffic shape question.
hello, thanks for your time. i've got an existing frame-relay network with about 100 endpoints and i have a project to convert the head-end host DLCI circuit from a frame-relay T1 to an ATM DS3. The DS3 is in place and I have good end to end communication to my test frame-relay circuit, but i have a question regarding shaping. on my old frame-relay circuit i used frame-relay map classes to specify how large each PVC was. what is the equivalent for ATM? here's what i currently have:
interface ATM4/0.650 point-to-point
description Test Frame
ip address 172.16.1.73 255.255.255.252
no ilmi manage
the only thing slightly puzzling is that "64" is the lowest setting i can specify. nearly all of my remote circuits are 56k, so i don't know how well that would work. what if i only had a 32k PVC? what then? is there a different way i should do this?
also, currently we use end-to-end keepalives over the frame-relay connections, but i can't find an equivalent feature for ATM that makes it work, is there one? or do i have to unconfigure end-to-end keepalives for all these PVCs?
