That's hard to triage such kind of bugs without of knowledge of particular backend.
Is there an evidence that neutron needs to be fixed and it's not a backend issue?

Title:
  Traceback when creating VxLAN network using CSR plugin

Status in OpenStack Neutron (virtual network service):
  Opinion

Bug description:
  OpenStack Version: Kilo

  localadmin@qa1:~$ nova-manage version
  2015.1
  localadmin@qa1:~$ neutron --version
  2.3.10

  I’m trying to run the vxlan tests on my multi node setup and I’m
  seeing the following  error/traceback in the
  screen-q-ciscocfgagent.log when creating a network with a vxlan
  profile.

  The error complains that it can’t find the nrouter-56f2cf VRF but it
  is present on the CSR.

  VRF is configured on the CSR – regular VLAN works fine
