Drag and Drop Question
Refer to the exhibit. The engineer is automating BGP peering on an OpenConfig device over RESTCONF. The model shows the bgp/global/config/as leaf for the local AS and the keyed neighbors/neighbor[neighbor-address]/config/peer-as list for neighbors. The engineer must construct an XML payload that sets local AS 65001 and adds neighbor 192.0.2.2 with peer-as
65002. Drag and drop the code snippets from the bottom onto the boxes in the code to construct the artifact. Not all options are used. Options may be used more than once.

正解：

Explanation:
In the OpenConfig BGP model, the XML payload must start with the bgp container in the BGP namespace. The local autonomous system is configured under global/config/as, so the correct element is as. The neighbor entry is keyed by neighbor-address, and the remote autonomous system for that neighbor is configured with peer-as under the neighbor's config container. The payload then closes the root bgp container.
