SI v2: attaching a static route to SI interface doesnt advertise the same

[Senthilnathan Murugappan]

static route added to service instance interface type doesnt get advertised via service chain.
I have v2 service instance in-network service instance and i have added static route to left interface of the SI like we do for V1 service instance.

code snippet is as below
                static_rt = RouteTableType([RouteType(prefix=static_route,
                                          )]) if static_route else None
                left_itf = ServiceInstanceInterfaceType(virtual_network=vn_fqname,
                                                    static_routes=static_rt)
               si_prop = ServiceInstanceType(left_virtual_network=left_vn_fqname,
                                          right_virtual_network=right_vn_fqname,
                                          interface_list=[left_itf, right_itf],
                                          ha_mode='active-active')
             self.obj = ServiceInstance(name=name, parent_type='project',
                                       fq_name=fq_name,
                                       service_instance_properties=si_prop)
             self.obj.set_service_template(self.vnc.service_template_read(id=st_uuid))
             self.uuid = self.vnc.service_instance_create(self.obj)

and observed that the static route was never published in the left vrf. However if i had a NetworkRouteTable and attach it to VN it works. Unable the test the same using InterfaceRouteTable due to #1544472

Checked with Rudra, this isnt supported with V2. One has to use InterfaceRouteTable in case of V2 service chain.
