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

IP-EIGRP Topology Table for AS(1)/ID(20.20.20.20)

Codes: P - Passive, A - Active, U - Update, Q - Query, R - Reply,

r - reply Status, s - sia Status

P 1.1.1.0/24, 1 successors, FD is 2560000256

via Redistributed (2560000256/0)

P 2.2.2.0/24, 1 successors, FD is 128256

via Rconnected (128256/0)

P 3.3.3.0/24, 1 successors, FD is 2297856

via 192.168.1.2 (2297856/128256), Serial1

P 20.20.20.0/24, 1 successors, FD is 128256

via Rconnected (128256/0)

P 192.168.0.0/24, 1 successors, FD is 2169856

via Rconnected (2169856/0)

P 192.168.1.0/24, 1 successors, FD is 2169856

via Connected, Serial1

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

Thanks.
