Question 59 Discussion

The exhibit shows the BGP configuration on the hub in a hub-and-spoke topology. The administrator wants BGP to advertise prefixes from spokes to other spokes over the IPsec overlays, including additional paths. However, when looking at the spoke routing table, the administrator does not see the prefixes from other spokes and the additional paths. Which three settings must the administrator configure inside each BGP neighbor group so spokes can learn the prefixes of other spokes and their additional paths? (Choose three answers)

  • A. Set additional-path to send
  • B. Set additional-path to forward
  • C. Enable route-reflector-server
  • D. Enable route-reflector-client
  • E. Set adv-additional-path to the number of additional paths to advertise
Correct Answer: A,D,E

To let spokes learn prefixes (including additional paths) from other spokes in a hub-and-spoke BGP setup, the hub must act as a route reflector and advertise all available paths, not just one.

To do this, three key settings are needed:

route-reflector-client – so the hub reflects routes between spokes.

additional-path send – allows the hub to send multiple paths.

adv-additional-path – defines how many additional paths to send.
