Click the Exhibit button.
Referring to the exhibit, you are receiving the 192.168.0.0/16 route on both R3 and R4 from your EBGP neighbor. You must ensure that R1 and R2 receive both BGP routes from the route reflector.
In this scenario, which BGP feature should you configure to accomplish this behavior?
To ensure that R1 and R2 receive both BGP routes from the route reflector, you should configure the 'add-path' feature. This feature allows the advertisement and/or reception of multiple paths to a destination from the same BGP peer, rather than only the active path. By using this feature, the route reflector can send both received routes (from R3 and R4) to R1 and R2, fulfilling the requirement.
i think answer C not A : because A allow add path addtional
requirement is that R1,R2 receive both routes (no LB mentioned) by default, the RR will perform best-path selection and will send only one route to R1,R2. So we need add-path on route-reflector A - correct answer
answer C
A. Enable advertisement and/or reception of multiple paths to a destination to/from the same BGP peer, instead of advertising/receiving only the active path to/from the same BGP peer.
