Question

You are given a simplified YANG data model for BGP configuration:

container bgp {
  leaf local-as { type uint32; }
  list neighbor {
    key "peer-address";
    leaf peer-address { type inet:ipv4-address; }
    leaf remote-as { type uint32; }
    leaf description { type string; }
  }
}

You must produce a JSON instance (RFC 7951 style) that configures local-as 65001 with two neighbors: 192.0.2.1 (remote-as 65002) and 192.0.2.5 (remote-as 65003, description "transit"). Which JSON representation correctly reflects this model?

Accepted Answer

{ "bgp": { "local-as": 65001, "neighbor": [ { "peer-address": "192.0.2.1", "remote-as": 65002 }, { "peer-address": "192.0.2.5", "remote-as": 65003, "description": "transit" } ] } }

Answer

{ "bgp": { "local-as": 65001, "neighbor": { "192.0.2.1": { "remote-as": 65002 }, "192.0.2.5": { "remote-as": 65003, "description": "transit" } } } }

Answer

{ "bgp": [ { "local-as": 65001 }, { "neighbor": [ "192.0.2.1", "192.0.2.5" ] } ] }

Answer

{ "bgp": { "local-as": "65001", "neighbor": [ { "peer-address": "192.0.2.1", "remote-as": "65002", "description": null }, { "peer-address": "192.0.2.5", "remote-as": "65003", "description": "transit" } ] } }
