Question No.52

Click the exhibit. Router R6 is a route reflector for clients R1, R2 and R5 with local preferences 100, 200 and 500 respectively. Router R3 advertises prefix 192.168.1.0/27 to routers R1, R2 and R5 which are configured with advertise-external. Routers R4 and R6 are both configured with quot;add-paths ipv4 send 2 receivequot;. Which routes to 192.168.0.1/27 is router R4 expected to have in its BGP routing table?

image

  3. The routes from routers R2 and R5.

  4. Two routes are chosen at random and advertised to router R4.

Correct Answer: C

Question No.53

Which of the following best describes the purpose of advertise-external?

  1. It enables a BGP speaker to advertise multiple external routes to iBGP peers.

  2. It enables a BGP speaker to advertise its best external route to iBGP peers when the best overall route is internal.
