Hi, let's assume this scenario. Central location is connected to FR netowrk with port speed 2Mbps. And remote location is connected with port speed of 64kbps. CIR between them is 32kbps. This is exact case for FR traffic shaping so central location will not overwhalm remote location with burst of data. In cisco book (CCIE practical studies, 2 examples), I read that for mincir value I need to put real CIR (32kbps) and for CIR parameter I need to put local port speed (in this case 2Mbps). In this case it should look like: frame-relay cir 2000000 frame-relay mincir 32000 Isn't this wrong ? What would be the point of this. With this config, central location will send data as fast as it can and will definitely overvhalm remote location with data. Shouldn't I put port speed of remote location for cir (64kbps). frame-relay cir 64000 frame-relay mincir 32000 thanks, jura
