Hi Iwase,
Looks like two ryu app file also doesnt work. I think, RYU treated as a
single context.
=========================================================
loading app app1.py
loading app app2.py
instantiating app app2.py of BGPRouter2
API method core.start called with args: {'waiter': <ryu.lib.hub.Event
object at 0x7f0a1e821908>, 'cluster_id': None, 'bgp_server_port': 180,
'local_pref': 100, 'local_as': 65001, 'label_range': (100, 100000),

Let me try as a separate process..
