When the OvS is standalone it works without a problem. However, when I connect it to the ONOS controller, pings do not reach the CSR1K. With some testing, it appears when connected to the controller, it is not sending the vlan tags. If I go to the CSR1Kv and configure VLAN10 as the native vlan, then VLAN 10 can ping the interface.
