A network administrator is auditing an enterprise multi-protocol routing environment. Match each dynamic routing protocol on the left with its corresponding default administrative distance, primary metric calculation method, and underlying algorithm on the right.
- Internal EIGRPDefault AD of 90; uses a composite metric based on minimum bandwidth and cumulative delay via DUAL.
- eBGPDefault AD of 20; relies on path attributes including Autonomous System path lists via a path-vector algorithm.
- OSPFDefault AD of 110; uses cost calculated from reference bandwidth divided by interface bandwidth via Dijkstra's SPF algorithm.
- RIPv2Default AD of 120; uses hop count as its sole metric with a maximum limit of 15 hops via the Bellman-Ford algorithm.
Cevap
Internal EIGRP matches Administrative Distance 90 with composite bandwidth/delay metrics; eBGP matches Administrative Distance 20 with path-vector AS-Path metrics; OSPF matches Administrative Distance 110 with cost metrics via Dijkstra; RIPv2 matches Administrative Distance 120 with hop count metrics via Bellman-Ford.
Each dynamic routing protocol correctly maps to its standardized default Administrative Distance (eBGP=20, Internal EIGRP=90, OSPF=110, RIPv2=120) and matching metric/algorithm characteristics.
