Tom,
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
Hello,=20
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 =
connectivity.
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.=20
Thanks,=20
