Question Image

An engineer working on a client’s network is trying to resolve the BGP community issue on the R1 and R2 routers. After displaying the BGP entries, the engineer notices that the two routers still produce different outputs. Which action must the engineer perform on either router to correct the problem and obtain the same output?

  • A Execute the lp bgp-community new-format command in Router1.
  • B Remove the lp bgp-community new-format command in Router1.
  • C Advertise the route to Router2 as standard community.
  • D Advertise the route to Router2 as extended community.
Explanation

BGP standard communities are 32-bit values. Cisco IOS displays them as a decimal number by default, whereas ip bgp-community new-format displays them in AA:NN format. R1’s decimal communities correspond to R2’s AA:NN communities, so enabling the new display format on R1 makes the outputs match. This affects display format, not community advertisement or exchange.
