Can a VIP and Pool Members in different route domain.

Hi,

Traffic forwarding between route domains

Forwarding of traffic between route domains is by default enabled between route domains in a parent-child relationship only. (That is, traffic received in a child route domain can be forwarded to a parent route domain and the reverse.) Consequently, by default, the BIG-IP system does not load balance traffic arriving in route domain 1 to servers in any other route domain, except for the parent route domain.

You can control this behavior by configuring the Strict Isolation feature of a route domain. For example, to allow traffic forwarding between route domains 1 and 2, (without making route domain 2 a parent of route domain 1 or route domain 1 a parent of route domain 2), you must disable the Strict Isolation property on both route domains.
