I used to be pretty good with VLSM addressing, but it's been a while since I've looked at it and I'm confused. I don't have a problem subnetting an existing subnet into equal subnets, but I need some help in subnetting with variable subnets. For exam...

Does anyone have any experience with Committed Access Rate (CAR)? I have a 2651XM and need to dedicate a certain % of Bandwidth to one FE port and give the rest to the other FE port. Any suggestions or help in configuring would be appreciated.
