That really threw me was that I used 1000 for the bandwidth metric in
the RIP redistribution, I played with the Delay on both links out of R4
and set R1, R5 delay to 1, but could not get anything to stay under the
FD on R4. Increasing the redistribution metric to 10000 and calculating
the metrics worked, but with much effort.
Your suggestion for setting both the BW and delay to 1 and working up
would have worked easier. I know now that this could be a good time
waster on the real test and leave for later.
Thanks.

I could try to give you an explanation, but I'm a mere mortal. Gen.
Brian
Dennis himself gave a beautiful, memorable, and generally "one for the
ages"
description in the solutions guide.
I believe this one wanted 4:1 ratio? Well you need to quickly do
something
to get the metrics in about that ratio? I changed bandwidth and delay
until
I got my solution.
Try setting bandwidth to "1" and "delay to 1" and then increasing every
so
small along different points until the router you want to effect the
changes
on (the one running the eigrp metric calculation) works once the
conditions
are met, and it has the variance command.
Don't forget,

Subject: EIGRP variance load sharing help
Can anyone offer any insight on how to quickly determine the EIGRP
metrics for a particular variance load sharing ratio. I struggled with
the IE lab 8 EIGRP variance question and ended up trying different
delays and bandwidth and ultimately calculating them to figure out the
question. However, this could eat up time if this was the real test.
Is there a quick rule or procedure for getting a particular metric and
load sharing ratio? In particular, Is there a way to avoid going over
the FD?
Thanks.
