In my lab I have 2 routers connected to switch A, all running eigrp. The routers each constitute a valid path via which the switch can reach switch B on the other side of the two routers.
The metrics on the router interfaces leading to switch A are set to reflect one ISP with a bandwidth of 15MB and another ISP with a bandwidth of 6 MB.
The ip eigrp top all on Switch A shows only one router being feasible. The other router's AD is so much lower than the FD of the successor that it won't be considered, no matter the variance.
The problem is: other than exactly equal metrics, I can't put in a bandwidth/delay value pair on the 6MB router that creates an AD that allows it to ever become a feasible succesor. IF I set the metrics exactly equal, then it will balance "proportionately" over the two lines, which clearly would be a bad thing when there is such a differential in bandwidth rates.
Without adjusting the K values which we are warned never to do...how on earth do I make it proporionately load balance these two links?
I'm thinking that the feasibility requirement, necessary to prevent loops, pretty much makes the unequal load balance feature a null and void advantage...
