Jay,

You need to find out if the router has ports active, for instance take a
look to this code:

def delete(self, request, obj_id):
	try:
		router_id = self.table.kwargs['router_id']
		port = api.neutron.port_get(request, obj_id)
		if port['device_owner'] == 'network:router_gateway':
			api.neutron.router_remove_gateway(request, router_id)
		else:
			api.neutron.router_remove_interface(request, router_id, port_id=obj_id)




Regards,

Edgar
