Hello, I am just wondering what the purpose is of using the 'shape peak' command on a WAN uplink interface.
For instance, if you have agreement with the service provider for a 20Mbps WAN uplink, why would you bother shaping the traffic to 20Mbps ?
Is it solely to prevent overruns and packet loss in case your outvound traffic exceeded what your service provider plan was ?
Thanks for any info.

The purpose of shaping, in general, or peak shaping, specifically?

Not so much to prevent as to allow you, rather than your SP, to manage any congestion.
