eigrp metric

Hi All,

I happen to find that my eigrp metric seems not correct. The metric should not too large. even the connected interface, 192.168.1.0/24, FD is 2169856. and the subnet just connected to my normal serial port! and the bandwidth is 1544kbit and the delay is 20000 usec. so using metric=[(10000000/bandwidth)+(delay/10)], the metric should less 10000!

but the following is the output: can anybody tell me what's wrong?

sh ip eigrp topo

Re: eigrp metric

Unlike IGRP, EIGRP multiplies its metric by 256. If you divide that number by 256 then you are right, your metric is 8476.

Thanks.
