VRF delete from EPG and re-adding VRF to EPG fails intermittently

Symptom Condition Workaround

  1. Update EPG for operation vrf-add.
  2. Update EPG for operation vrf-delete.
  3. Update the same EPG again with operation vrf-add for the same VRF which was deleted in step 2.
Wait of 30 seconds between the EPG update vrf-add and vrf-delete operations on the same EPG.
