• Question 794:

  A router is configured with the command "configure router ecmp 4". There are two best paths to a given destination with an equal cost in the IGP. Which of the following best describes the handling of traffic to this destination?

  A. The router installs two routes for the destination with two different next hops. A hashing algorithm is used to distribute traffic over the two paths.

  B. The router installs two routes for the destination with two different next hops. Traffic is evenly distributed over the two paths.

  C. The router installs four routes for the destination with four different next hops. A hashing algorithm is used to distribute traffic over the four paths.

  D. The router installs four routes for the destination with four different next hops. Traffic is evenly distributed over the four paths.

  E. The router installs one route for the destination. Traffic is evenly distributed over the two paths.

  Correct Answer: A

  A. Router R6 to router R3 will follow (R6-R5-R2-R3). Router R3 to router R6 will follow (R3- R2-R5-R6).

  B. Router R6 to router R3 will follow (R6-R5-R2-R3). Router R3 to router R6 will follow (R3- R4-R2-R5R6).

  C. Router R6 to router R3 will follow (R6-R5-R2-R3). Router R3 to router R6 will follow (R3- R4-R7-R5R6).

  D. Router R6 to router R3 will follow (R6-R5-R7-R4-R3). Router R3 to router R6 will follow (R3-R4-R7-R5R6).
