I’m working on the following lab in GNS3vault:
I understand the video solution and it makes total sense. However, there seems to be a problem on router Perth. All redistributed routes show up twice in the routing table as a result of equal-cost load balancing. The instructions say that the most optimal route should be used. However, we can’t use route-maps, distribution lists, or prefix lists. The only way I know of having these distributed routes with only one entry in the routing table is to either use a static route or the maximum-paths command. I thought maximum-paths would work but when the path type and path cost are the same it seems to keep first learned route in the routing table which may not always be optimal. How can I achieve optimal routing on Perth while fulfilling the requirements of the lab?
