If you want the end result to be (let's pick even numbers for simpler math!) EIGRP using 500K, then you would set your bandwidth to 1000K. So if you want 40% of a line that is typically 1.5M, you would take 1.544M * .40 then multiply that number by 2 to compensate for the end-effect of 50%. So 1234 would be the bandwidth of the line. 617 would therefore be the bandwidth that EIGRP actually used. HTH,

If in a question ; we are asked to configure a router so that EIGRP uses say 40 % of bandwidth on serial interface . we know that default is 1.544 mbps on a serial .. are we supposed to do 0.4 * 1.544 and configure that under serial interface i.e int s0/0/1 bandwidth 617 or we need to say int s0/0/1 band 1234 taking into account of 50% funda of eigrp ? Please clearify as these small quest can sometime create confusion Gaurav Madan
