A network administrator is documenting core dynamic routing protocol classifications for an enterprise network audit. Match each dynamic routing protocol on the left with its corresponding path-selection algorithm and primary operational attribute on the right.
- OSPFOperates as an interior link-state protocol using Dijkstra's Shortest Path First algorithm to build a complete topology map of the area.
- BGPFunctions as a path-vector exterior gateway protocol that relies on Autonomous System path length and policy attributes for routing decisions.
- EIGRPUtilizes the Diffusing Update Algorithm (DUAL) to deliver fast convergence and maintain loop-free backup routes based on bandwidth and delay metrics.
- RIPv2Calculates best paths using pure distance-vector metrics based on hop count, with a maximum allowable hop count limit of 15.
Answer
OSPF matches with the link-state protocol using Dijkstra's algorithm; BGP matches with the path-vector exterior gateway protocol using AS path attributes; EIGRP matches with the protocol utilizing the DUAL algorithm and composite bandwidth/delay metrics; RIPv2 matches with the distance-vector protocol using hop count capped at 15.
Each routing protocol matches its exact architectural behavior: OSPF is a link-state protocol using Dijkstra's SPF algorithm; BGP is an exterior path-vector protocol using AS-Path attributes; EIGRP is an advanced distance-vector protocol using DUAL and bandwidth/delay metrics; RIPv2 is a distance-vector protocol capped at a 15-hop limit.
