Refer to the exhibits, which contain the network topology and BGP configuration for a hub.
An administrator is trying to configure ADVPN with a hub and spoke VPN setup using iBGP. All the VPNs are up and connected to the hub. The hub is receiving route information from both spokes over iBGP; however, the spokes are not receiving route information from each other.
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. Enable route redistribution under config router bgp. B. Configure the hub as a route reflector. C. Configure auto-discovery-sender on the hub. D. Add a prefix list to the hub that permits routes to be shared between the spokes.
