Border Gateway Protocol Fundamentals

In the diagram, BGP import policy north-and-south is applied on router R5. Router R1 advertises prefix 140.100.1.0/24 with community 65200:1. Which statement about router R5's processing of the received route update for prefix 140.100.1.0/24 is TRUE?

Question Image

  • A The prefix is rejected.
  • B The prefix's local preference is set to 20.
  • C The prefix's community value is removed.
  • D The prefix's community value is modified to 65200:2.
Explanation

The policy’s north entry matches community 65200:1 and accepts the route while setting its local preference to 20. Since the advertised route carries that community, it matches this entry; the policy does not remove or alter the community.
