Severity: 3-Major


DHCP traffic can traverse between route domains, e.g., when working with a route domain with a parent. Under certain circumstances, this is not desired.


The DHCP server side flow might get established to the parent route domain, and will persist even after the route in its own route domain becomes available again.


DHCP relay in use on a route domain with a parent relationship or strict isolation disabled.


There is no workaround at this time.
