iRule for combination of FQDN pool member and route domains

Hi,

As per you mention "As soon as I created the FQDN pool member, I noticed that the dynamically created node, created as a result of the FQDN resolution IP, was assigned the default route domain '0'."

From my experience with route domain + partition and refer from F5 article =>

https://techdocs.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/tmos-routing-administration-11-6-0/8.html

When you configure partition. You can set default route domain for each partitions.

====================================================================================

From the Partition Default Route Domain list, select either Another route domain (0) is the Partition Default Route Domain or Make this route domain the Partition Default Route Domain. This setting does not appear if the current administrative partition is partition Common. When you configure this setting, either route domain 0 or this route domain becomes the default route domain for the current administrative partition.

====================================================================================

When you create any object in partition e.g. virtual address, selfip, pool member, node. F5 will applied all those object to partitiion default route domain that is not the common.

If you configure F5 with above setting. You will not face issue as you explianation.
