​​Summary:

1. Verify the impact of auto-summarization, then disable it

2. Add a manual summary route at the Eggs router. The more specific the route, the better tasting your eggs.

- Any time a summary table is created via eigrp auto-sum, the router adds the summary route to the routing table pointed to Null0 (garbage, this is not good)

 

1. Eggs, Ham, Bacon, Toast, and Cereal:

router eigrp 90
  no auto-summary
 

 

2. Add a manual summary route at the Eggs router. The more specific the route, the better tasting your eggs.
