Description (partial)

After a disruptive upgrade on the VPC primary switch on Vxlan fabric from 7.0(3)I7(5a) to 9.3(2), the Remote NVE Rmac for all VLANs are missing from MAC address-table and L2FM. BGP/NVE and L2RIB have the correct info.

The issue seems to have a very low occurrence. Exact condition is unknown.
On this scenario only VPC primary was upgraded and secondary stayed on old release.
