The eigrp delay seems giving me problems when I toggle the Cat6509 Sup720 to
secondary Sup720. The log files shown EIGRP K-value mismatch for all routers
that I'd make the changes to the delay parameters. For instance, delay 15000
on router_A f0/0 and delay 10000 on Cat6509 f1/1.
Note: it is working fine normally without any EIGRP K-Value mismatch but
except reboot the primary sup.
The eigrp K3 (delay) value is consider mismatch when point-to-point link was
configured by using different delay setting? I just try to think from
unidirectional way and by right the eigrp metrics is different for up/down
link.
Appreciate anyone who able to contribute ideas on this.
Regards,
Danny

Danny,
When you say, "eigrp delay", do you mean the delay on the interface eigrp
using to calculate it's metric?
The eigrp K-value is used to specify how much importance to give a component
of the eigrp metric. As you know, eigrp has several components such as
bandwidth, load reliabitlity, and delay it can use to determine it's metric.
By default, not all componenets are used because the K-value for those
unused component is zero. So, by default, eigrp says the "importance" of
all components except bandwidth and delay is zero because the k-value for
those components is zero.
However, the "importance" of bandwidth and delay is, by default, 1 because
those components of the metric have a K-value of 1.
Now, if you wanted eigrp to consider bandwidth twice as important as delay,
for example, you would make bandwidth's K-value twice as large as the
delay's K-value.
Now, if the K-value of all eigrp routers aren't the same, you'll have
problems because now the eigrp routers aren't using the same formula to
compute metrics making the metric meaningless.
If you look in the doc cd under eigrp commands, you'll find the formula
eigrp uses to compute it's metric. I think the command is metric weigth.
HTH, Tim
