Primary NAPT switch role information is not updated to any Stand-by switch when the primary NAPT is rebooted

EFFECT:
Once a Primary switch is selected for a VRF, if this switch is lost all communication for that VRF (SNAT) is also lost, and there is not updated to any other switch.
For example a VM configured with SNAT in compute-0-5 can not communicate using SNAT if the primary switch compute is lost.
In the tests done primary switch was compute-0-6. While compute-0-6 is being rebooted or lost communication VMs using SNAT in any other compute can not communicate. switch Primary role is not updated to other switch.
Once compute-0-6 is back into service it takes the primery switch role and SNAT communication is restablished.

DESCRIPTION:
When Primary switch in the VRF is lost, the information is not updated to any other switch in the cloud.
