 Description   

Overview:
---------
Internal VM IP doesn't have a flow in T21.

Steps:
------

  • Created 3 networks + public/external network
  • Created router connected to 3 networks + to public/external network
  • Created 6 VMs. 2 VMs on each of the network
  • All VMs has FIP
  • Started running inter connectivity ping checks
  • Started running ping checks to FIPs

Expected results:
-----------------

  • All connectivity checks works

Actual results:
---------------

  • For one VM with internal IP 3.3.3.211 flow was missing in T21 and therefore internal connectivity to it and ping to its FIP wasn't working

Caused by a temporary deletion of tunnel interfaces when updating transport zones.
Should be fixed by: https://git.opendaylight.org/gerrit/#/c/48952/
