CCNA 3.2.f: Metric


The metric is a value produced by the routing protocol's algorithm.  The metric value determines the best path to a destination network within a routing protocol.

  • To determine the metric:
    • RIP uses hop count
    • EIGRP uses K values
    • OSPF uses reference bandwidth
  • Metric is used to compare routes to a destination by the same routing protocol
  • Lower values indicate preferred routes
  • Examples:
    • In the diagram, RIP has 1 hop count to get to network  It's the 1 in [120/1].
    • RIP has 2 hop counts to get to network and It's the 2 in [120/2].
