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.
