The link below gives the formula for EIGRP metric. From that you should be
able to calculate the value required.

Hi group,

  R4
/ |
R5 | (shared eth between r4 & r8)
\ |
  R8

This is a hub & spoke topology, where r5 is hub, while r4 & r8 are spokes.

Now on r5, it sees the r4 / r8 ethernet's as:-

D 172.168.48.0/24 [109/2195456] via 172.168.200.8, 00:00:09, Serial0.2

                  [109/2195456] via 172.168.200.4, 00:00:09, Serial0.2

Now, if I want to increase the EIGRP metric of both routes to say, 2200576,
I know that I can do this by using an "incoming" offset-list on r5

offset-list <x> in 5120 , where 2200576 - 2195456 = 5120

However, if I want to accomplish this by modifying the EIGRP Delay metric on
both r4 r8, is there any formula or calculations that I could done so I
know what value to put in for "Delay" metric in order to get 2200576?

Regards,
H.
