Jason:
The feasible distance is equal to the advertised distance (or reported
distance , depending which book you read) by R6 + the metric it takes to
reach R6 .
In other words, changing the delay on the serial of r6 will have no impact
on the metric. What you have to do is change in on the serial of r2.
But obviously in your case the load balancing will still occur even if you
do the change on the serial of r2 as it is a multipoint link to r5 and r6.
In order to make r2 prefer r5 in your case would be to change the delay on
R6 ethernet interface( example on the 150.50.7.0 subnet)

Subject: EiGRP metric - delay on serial
I am trying to alter the metrics of a route in the IPE Lab 7. R2 is
rcv'ing routes from R5 and R6 via serial links. I change the delay on
the serial interfaces of R6 to have R2 prefer the route to R5, but it
has no effect:
r2#si
150.50.0.0/16 is variably subnetted, 7 subnets, 4 masks
D 150.50.4.0/24 [90/2733056] via 150.50.100.5, 00:00:07,
Serial0.256 R5
[90/2733056] via 150.50.100.6, 00:00:08,
Serial0.256 R6
D 150.50.7.0/25 [90/2195456] via 150.50.100.5, 00:00:18,
Serial0.256
[90/2195456] via 150.50.100.6, 00:00:18,
Serial0.256
D 150.50.5.64/27 [90/2707456] via 150.50.100.5, 00:00:08,
Serial0.256
[90/2707456] via 150.50.100.6, 00:00:08,
Serial0.256
Then change the delay on the serial link on R6:
r6#conf t
Enter configuration commands, one per line. End with CNTL/Z.
r6(config)#int s1/0
r6(config-if)#delay 100000
r2#clear ip ro *
r2#si
150.50.0.0/16 is variably subnetted, 7 subnets, 4 masks
D 150.50.4.0/24 [90/2733056] via 150.50.100.6, 00:00:01,
Serial0.256
[90/2733056] via 150.50.100.5, 00:00:02,
Serial0.256
D 150.50.7.0/25 [90/2195456] via 150.50.100.6, 00:00:02,
Serial0.256
[90/2195456] via 150.50.100.5, 00:00:02,
Serial0.256
D 150.50.5.64/27 [90/2707456] via 150.50.100.6, 00:00:02,
Serial0.256
[90/2707456] via 150.50.100.5, 00:00:02,
Serial0.256
Changing the serial interface delay on S1/0 of R6 to had no affect! IS
something wrong here?
Serial1/0 is up, line protocol is up
Hardware is cxBus Serial
Internet address is 150.50.100.6/27
MTU 1500 bytes, BW 1544 Kbit, DLY 1000000 usec,
Now when I change the delay on the Ethernet interface (ingress path of
route) the metric is changed, but I thought all paths were considered
when tallying delay.
