I´ve the following setup:
ISP-ROUTER+-------+ My-ROUTER +-------+ ...
The available bandwidth between ISP-Router and MY-ROUTER is 50Mbps. The Physical link is 1000Mpbs. All above 50Mbps result in additional costs.
The plan is to limit the traffic. With the following config the upload traffic is shaped and limited to 50Mbps.
shape average 50000000
service-policy output QOS_TO_ISP
I tested it and it worked. But how i can limit the download traffic? Sure, i could police the traffic in input direction so all traffic above the limit will be dropped from MY-ROUTER, but nevertheless this will not prevent the ISP Router to sent traffic above 50Mbps which will result in additional cost, is this correct?
