What is the purpose of the EIGRP Null0 summary route?
- to enhance security by hiding all internal networks that are included in a summary route
- to prevent routing loops for destination networks which do not actually exist but are included in a summary route
- to reduce bandwidth consumption for traffic that is leaving the network
- to ensure that all traffic destined for individual subnets uses one single best path
Explanation: The Null0 interface represents a route to nowhere. Using a route to the Null0 interface prevents routing loops for any destination networks present in the summary route that do not actually exist.
