Refer to the exhibits, which contain the network topology and BGP configuration for a hub.
Exhibit A.

Exhibit B.

What change must the administrator make to the hub BGP configuration so that the routes learned from one spoke are forwarded to the other spoke?

  • A. Configure the hub as a route reflector
  • B. Configure auto-discovery-sender on the hub
  • C. Add a prefix list to the hub that permits routes to be shared between the spokes

Selected Answer: A
iBGP rules disallow advertisement of any prefix learned from any iBGP neighbor to any other iBGP neighbor. This means you must create a full mesh (i.e., all iBGP speakers must peer with ALL other iBGP speakers in the ASN). Route reflection allows you to circumvent this restriction as route reflectors will advertise all iBGP-learned routes to all of its route-reflector clients.

They are asking about route from each other not being redistributed to each other, not the ADVPN dynamic connexion. And it shows that Route Reflector is not enabled

Selected Answer: B
You must enable set auto-discovery-sender if you want ADVPN. This setting indicates that when IPsec traffic transits the hub, it should send a shortcut offer to the initiator of the traffic to indicate that it couldperhaps establish a more direct connection (shortcut).
