HPE7-A06 · Question #87

Refer to the exhibit. What needs to be defined on Edge-1 to establish valid BGP routing between agg-sw1 and agg- sw2 using BGP protocol using the IP addresses described in the image above? A. B. C. D.

The correct answer is D. router bgp 65100 10.0.0.2 remote-as 65200 10.0.0.4 remote-as 65200 address-family ipv4 unicast neighbor 10.0.0.2 activate neighbor 10.0.0.4 activate. On AOS-CX, when using address-family ipv4 unicast, each BGP neighbor must be explicitly activated under the AFI/SAFI to exchange routes. Adding neighbor 10.0.0.2 activate and neighbor 10.0.0.4 activate on Edge-1 enables proper route advertisement between the two eBGP peers.

Explanation

On AOS-CX, when using address-family ipv4 unicast, each BGP neighbor must be explicitly activated under the AFI/SAFI to exchange routes. Adding neighbor 10.0.0.2 activate and neighbor 10.0.0.4 activate on Edge-1 enables proper route advertisement between the two eBGP peers.
