I can't seem to prove EIGRP is unequal load balancing, but I may be going about this the wrong way. Below is the router config I am attempting to load balance through. Data is coming from 198.22.166.6 and going to 10.10.10.254.
Doesn't the variance command, when set to 2, unequal load balance to links with a metric twice that of the best route?
I have two 'permit any' ACLs setup, one on S0/1 and the other S0/2 so I can see the counters tick up as packets are passed. But as traffic flows through this router, it is only routed through S0/1 to 10.10.10.254 (ACL 1 counter ticks up). The only way I can get traffic to go over S0/2 is to shutdown S0/1.
Am I doing something wrong?
