I was under the impression that, although MTU is not used in the routing formula for EIGRP, it is used as a final tie-breaker between 2 routes. If you did not want to use equal-cost load balancing, for whatever reason, MTU could be used to achieve this. The route with the highest MTU would be placed in the Routing table. Has anyone heard anything like this before?
