EIGRP uses the following formula to scale the delay:
delay = delay(i) * 256
where delay(i) is the sum of the delays configured on the interfaces, on the route to the destination network, in tens of microseconds. The delay as shown in the show ip eigrp topology or show interface commands is in microseconds, so you must divide by 10 before you use it in this formula. Throughout this paper, we use delay as it is configured and shown on the interface.
Delay is a static value ie it doesn't change dynamically.
If you do a "sh interface" delay is displayed in microseconds. You can change the delay of the interface to affect routing choices by EIGRP and this is considering teh most reliable way to affect metrics as opposed to changing the bandwidth which has knock on effects to things such as QOS.
All interfaces from the source to the destination have their delays included in the EIGRP metric calculation.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
