DHCP flows crossing route-domain boundaries might fail.


The second and subsequent DHCP clients requests will not be forwarded to the DHCP pool members.


Example of a configuration leading to the problem: - route-domain RD%2 with parent defined as route-domain RD%1. - Virtual-server in route-domain RD%2. - Pool member configured in RD%2 (sharing IP addressing with RD1) - DHCP client connects to the virtual-server in route-domain RD%2. - Route lookup for a pool member ends up with connection in route-domain RD%1


When configuring a DHCP pool member, use the ID of the parent route-domain (the one that will be returned by a route-lookup for the pool member's IP address).
