Altering DELAY to change routing metrics

[Jpeanut]

I am trying to alter the DELAY on a remote interface so that I can decrease my routing metric on a local router. Basically, I want the metric from Router A to Router C to decrease by adjusting the e0/0 delay from 1000 (eth) to 100(fast-eth) on Router C.

The current metric on Router A s1/1 (point-to-point)looks like this:

D 172.20.0.0/16 [90/2195456] via 172.16.200.10, 00:09:15, Serial1/1

I changed the delay on Router C's e0/0 to 100 but the routing metric hasn't changed. It should change to 2172416. Also when I do a sh int e0/0 on Router C, it still shows the DELAY at 1000 (but the sh run shows the delay 100 line for e0/0):

ROUTERC#sh int e0/0
Ethernet0/0 is up, line protocol is up
Hardware is AmdP2, address is 0050.5469.30a0 (bia 0050.5469.30a0)
Internet address is 172.20.2.1/24
MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec, rely 255/255, load 1/255

Anyone have any experience with this kind of stuff?? Thanks ahead.

It all depends on your routing protocol. The only protocols that will use delay are EIGRP and IGRP (both Cisco Proprietary). If you are using OSPF or RIP then changing the interface delay won't have any effect.

I forgot to mention I'm using EIGRP.

Since my explaination is difficult I have tried to revise it:

Using EIGRP:

Router A direct connects to Router C via a primary and secondary p2p T1s
Router A direct connects to Router B via p2p T1
Router B direct connects to Router A and Router C via p2p T1 to each

I want to alter the route metric on Router A so that the path to Router C gets load balanced also using the path through Router B. And so that I am utilizing a 4.5mb pipe instead of only a 3mb to Router C from A.

Current Router A route table:

D 172.18.0.0/16 [90/2172416] via 172.16.200.37, 3d00h, Serial3/0 to Router C pri
[90/2172416] via 172.16.200.6, 3d00h, Serial1/0 to Router C sec
D 172.21.0.0/16 [90/2195456] via 172.16.200.18, 2d22h, Serial2/1 to Router B

Here, only the path to Router C is load balanced because the route metric there is lowest [2172416] and heavy traffic doesn’t flow through Router B.

So I tried to modify the DELAY and BANDWIDTH on Router B to 100 and 100000 respectively, hoping to drop its metric from [2195456] to [2172416]…(Router C has DELAY of 100 and BW 100000 by default because it has a FastEth port instead of a standard Ethernet that Router B has).

But when I modify these values on Router B the metric does not change in Router A’s route table and I don’t know why.
