The row status variable is used according to installation and removal conventions for conceptual rows. When a Relay Entry is created by applying write operation on 'agentDhcp6InterfaceRelayAddr' and 'agentDhcp6InterfaceRelayIntf', row-status becomes 'active'. If row-status for a relay entry is set to 'destroy', the corresponding Relay Entry gets deleted.
