doesn't lock out traffic for such long periods of time.
Could it be that buffers and flow-control over the 14ms third party leg are causing the rate-limiting leaky bucket to continue to overflow long after it's full?
Or you are losing line protocol keepalives of some sort (e.g. at L2), or routing protocol packets. It may also be that your MPLS provider limits the traffic at X kbps INCLUDING protocol overhead - if so it's going to police out all sorts of important stuff (assuming you are running FR, ATM or something rather than some sort of TDM over MPLS).
Hey Alex, thanks for your reply . It's all IP over MPLS AFAIK, and we're using static routes to the site so I can't imagine it's either of these. We're going to traffic shape at the remote-end, so this should alleviate the problem. Just really wanted to check the line 'outages' could be caused by the nature of rate-limiting (looks like it can) and weren't indicitive of another underlying problem. Thanks, S
