Displaying Hardware Routes History
You can display the history of hardware routes in the RIB table. This becomes useful when troubleshooting hardware routing on the network.
CLI (network-admin@spine1)>vrouter-rib-history-show time 15:30
 
time caller reason ip prelen nexthop flags vlan intf_ip intf_id
