Question Image

You receive the BGP route displayed in the exhibit from four different upstream ISPs.

With reference to the exhibit, which ISP is chosen as the active path?

  • A ISP 2
  • B ISP 1
  • C ISP 4
  • D ISP 3
Explanation

BGP prefers the eligible route with the highest local-preference value before evaluating AS-path length or origin. The route through ISP 3 has local preference 200, exceeding ISP 4's 150 and ISP 1 and ISP 2's 100, so it is the active path. Juniper Networks: BGP Overview
