"service-function-forwarder-ovs:ovs-bridge":

{ "bridge-name": "br-test" }

,
"service-function-forwarder-ovs:ovs-node":

{ "node-id": "/network-topology:network-topology/network-topology:topology[network-topology:topology-id='ovsdb:1']/network-topology:node[network-topology:node-id='ovsdb://127.0.0.1:40087']" }

}
]
}
}

2. Try to GET the data from:
