I connect multiple sites through a full mesh MPLS cloud. My main site has a 45Mbps DS3 connection into the cloud and the other sites have varying speeds 2-20 Mbps. How do I prevent the smaller sites from being overloaded with traffic by the main sites?
Hi hr, can you be a little more specific. Are you saying that I should (on a per site basis) create class maps for all traffic (obviously I can use class default) and then a policy map with explicit bandwidth statements that equals the total bandwidth of the remote site? I only have a single connection into the MPLS cloud so I can only apply one "service policy output" to that interface and with 30 sites I am not going to be able to specify enough bandwidth for each site.
What I meant is that you need to identify the traffic destined to each spoke site, map it to a separate class-map and perform traffic shaping for each and every one of these class-maps (similar to per DLCI traffic shaping with FrameRelay). This is the only way you can guarantee that you will not overwhelm the remote site link.
