Hi All,
Below are the conclusions from my testing and I welcome any input.
The key is to adjust the metric/cost to "equal-metric" path if variance
command is not allow for EIGRP unequal-cost path load balancing.
1) Bandwidth command under EIGRP interface - if the path calculation is not
too complex, this is the easiest!
2) Offset-list command under router eigrp - use it when you need more
advance route control eg ACL, or when the bandwidth calculation is too
complicated (+- the metric definitely easier than */+)
3) If redistribution involved, tune the metric during the redistribution.
Thanks again for your time.
Ed.
