EIGRP and IGRP metric calculations
OK I am working on a lab set-up art the minute (comparing IGRP and EIGRP)
Quick question having setup IGRP and run the sh ip route (Ip address) command I get the following output: -
newport#sh ip route 172.16.1.1
Routing entry for 172.16.0.0/24
Known via "igrp 100", distance 100, metric 7700
Redistributing via igrp 100
Advertised by igrp 100 (self originated)

Routing Descriptor Blocks:
* 220.20.20.162, from 220.20.20.162, 00:01:09 ago, via Ethernet1
Route metric is 7700, traffic share count is 1
Total delay is 27000 microseconds, minimum bandwidth is 2000 Kbit
Reliability 255/255, minimum MTU 1500 bytes
Loading 1/255, Hops 2
obviously the metric itself is available however I used the IGRP metric calculation (using the default K values) to check it myself and as expected got 7700.
When I run EIGRP and run the sh ip route command (same IP address) I get the following: -
newport#sh ip route 172.16.1.1
Routing entry for 172.16.0.0/24
Known via "eigrp 200", distance 90, metric 1971200, type internal
Redistributing via eigrp 200

Routing Descriptor Blocks:
* 220.20.20.162, from 220.20.20.162, 00:00:38 ago, via Ethernet1
Route metric is 1971200, traffic share count is 1
Total delay is 27000 microseconds, minimum bandwidth is 2000 Kbit
Reliability 255/255, minimum MTU 1500 bytes

--------------------------------
Both are using the same default geteway but produce different overall metrics.
When I use the IGRP K value calcualtion on the EIGRP figures I still get 7700 as the metric, what am I doing wrong????
