A tax assessor’s EIGRP domain grew by dozens of neighborhood prefixes, and query scope is becoming painful. How does summarization at distribution primarily help scalability here?
Select an answer to reveal the explanation.
Short Explanation
Summaries draw a big circle around the new neighborhoods so the rest of the county doesn’t sweat every driveway change. Fewer specifics in the wider topology means quieter queries when something flaps inside. It’s a scalability fence, not an Internet-table dump.
Full Explanation
EIGRP summarization at distribution (or other logical boundaries) hides more-specific prefixes, shrinking topology tables and limiting how far queries about those specifics propagate. That improves scalability after rapid prefix growth. Summarization does not mandate full Internet tables on access routers, turn EIGRP into OSPF flooding, or require disabling authentication.
