Question

Which of the following routing technologies uses a successor and a feasible successor?

Options

  • AIS-IS
  • BOSPF
  • CBGP
  • DEIGRP

Explanation

Enhanced Interior Gateway Routing Protocol (EIGRP) is the routing technology that uniquely employs the concepts of a successor and a feasible successor. These terms describe primary and backup routes to a destination.

Common mistakes.

  • A. IS-IS (Intermediate System to Intermediate System) is a link-state routing protocol that uses a shortest path first algorithm but does not use the terms successor and feasible successor.
  • B. OSPF (Open Shortest Path First) is also a link-state routing protocol that calculates shortest path trees but does not use the specific terminology of successor and feasible successor.
  • C. BGP (Border Gateway Protocol) is an exterior gateway protocol that uses path attributes and policies for routing, not successor/feasible successor terminology.

Concept tested. EIGRP routing terminology (successor, feasible successor)
