Mobile backhaul architecture and technologies

When a router learns routes from a route reflector, what path must packets destined for the learned prefixes follow by default?

  • A To the next BGP hop
  • B To the BGP neighbor
  • C The Route Reflextor
  • D To the Next IGP hop
Explanation

A route reflector advertises BGP routes without normally changing the BGP NEXT_HOP attribute. Packets therefore follow the forwarding path toward the route’s next BGP hop; they do not inherently traverse the route reflector or the BGP neighbor that advertised the route.
