Bandwidth Control Question

My suggestion is to enable the full DS3 and have each router
traffic-shape to 6M on the neighboring interfaces.  Rate-limit on the
input of your router to disallow the customer from sending you more than
the limit.  Remember that for the most part rate-limiting polices, where
traffic shaping performs more buffering and shaping.  That's why you
should use the combo of a shape on the sender side and a police on your
side to protect.

Subject: Bandwidth Control Question



A customer of ours in the next building would like 6M of Internet
bandwidth from us, so we would wire a DS3 between the two buildings for

The question is: how to we control the amount of bandwidth that we give
them? Could we use rate limiting to contain the bandwdith to 6M, our
would we need to get external IDSU's to do that?

Note: we have a Cisco 7206VXR router on our end. The customer has a
Cisco 7513.
