Can you add the following:
Output of ovs-vsctl show and dump-flows on both nodes.
Netvirt Configuration details [specify if using default for all].
If this is a CSIT test case link to test rlogs.

Various logs from the openstack controller node when creating and attaching a router to a network using ODL boron 0.5.1-SNAPSHOT and ovs 2.5.9 on the node

This also happens in the OPNFV sdnvpn deployment.

This is the ODL features boot:
featuresBoot=‘config,standard,region,package,kar,ssh,management,odl-restconf-all,odl-aaa-authn,odl-dlux-all,odl-netvirt-openstack'

Steps to reproduce:

  • Create a network with a DHCP (ERRORS appear but DHCP works)
  • Create a router (No errors)
  • From the Horizon router panel, add an interface for the router to the Subnet
  • A lot of ERRORS appear (see attachments)
  • Enter the router namespace, try to ping the dhcp and fail

See the attachments for odl logs, ovs-vsctl show/list interface and for dump-flows output on br-int.

I've tested this in the OPNFV SFC deployment with boron, but that still uses the ovsdb implementation and this works there.
