  • Question
  • Two connected routers are configured with RIP routing. What will be the result when a router receives a routing update that contains a higher-cost path to a network already in its routing table?


  • Options
  • A. The updated information will be added to the existing routing table.
  • B. The update will be ignored and no further action will occur.
  • C. The updated information will replace the existing routing table entry.
  • D. The existing routing table entry will be deleted from the routing table and all routers will exchange routing updates to reach convergence.

  • Correct Answer
  • The update will be ignored and no further action will occur. 

    Explanation
    When a routing update is received by a router, the router first checks the administrative distance (AD) and always chooses the route with the lowest AD. However, if two routes are received and they both have the same AD, then the router will choose the one route with the lowest metrics, or in RIP's case, hop count.
