F5 Route domain - using the same IP in multiple route domain on same LTM

Hello Experts, As per the F5 DOC regarding the rotue domain it function as like a VRF and we can use duplicate IP addresses on the network, because each of the duplicate addresses resides in a separate route domain and is separated from the network.

I have tried to configure the same VLAN and IP on two different route-domain. for exmaple vlan 10 with an IP 10.10.10.1 on Route domain 0 and route domain 20 but for some reasons I'm getting an error while using the same VLAN on the other route domain.

Could you please help me to know whether I can use the same VLAN and same IP block on different route domain on same LTM?
