Same vlan in multiple route domains

I don't think this is possible based on the link mentioning it needs to be separate vlans. https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/tmos-ip-routing-administration-11-2-0/2.html

I am using a vlan for management. The LTM won't let you create vips on the same subnet as your management by default without route domains. (I know I've gotten around that before in the lab but don't remember how). I'm trying to use the same vlan (mgmt. vlan) in a separate partition & route domain, untagged on the trunk. However it isn't working (can't get to gateway). VLAN is untagged on the switch to the data trunk going to the F5. Obviously mgmt. port is separate and an access port.

Should I be able to send data traffic untagged on the data trunk link on the vlan that's also being used by the mgmt.? But out the dot1q trunk?
