Question 22

Click the Exhibit button.

Referring to the exhibit, from which device(s) does R3 learn about Route X?

    Correct Answer: B

    R3 learns about Route X from R1 only. In an iBGP (Internal Border Gateway Protocol) environment, routers do not forward iBGP-learned routes to other iBGP neighbors to avoid routing loops. This rule means that while R1 can learn Route X from the router in AS 64502 and then advertise it to R2, R2 will not forward this route to R3. Therefore, R3 will receive information about Route X solely from R1.
