I will look at this way. I will prefer in the following order.
(1) offset will affect EIGRP formula result and plus more granular to the
specific routes. And the best advantage is it will not affect anything else.
(2) Delay is my second choice and that will affect all the routes but not QOS.
(3) bandwidth : affect all the routes plus QOS settings
Please let me know if I am missing anything. :-)

Rob,
I think offset-list would be fine. Remember when you alter interface
parameters, especially bandwidth you may impact other protocols or
configurations (e.g. qos).

I was working on Vol 3 Lab 3 Question 3.2. I configured my lab slightly
different then the way it is in the Proctor guide. Now I am starting to think
of a reason my solution may come back and bite me later. Here is what I did:
I used an offset list in that was applied to the Ethernet port so that it is
slightly higher in it’s metric
I configured a variance of 2 to it would balance between the two (and it does)
Configured traffic share so traffic will only use only the serial connection,
yet still show both in the routing table (as per the question)
That appears to work with just the single route.
Now the Proctor guide did it by changing the bandwidth and delay of the
Ethernet connection instead of the off set list
My question is this: is there a configuration out there that would make min
fail since I have a set offset value? Currently I believe that the metric
between the two routers are always the same and it really does not matter what
is behind each. If I send a route through EIGRP and it uses that link then it
will add the same values to the metric and it will still work.
Guess I am just second guessing my self but would like someone else’s thought
on the topic
Rob
