HA Cluster Irules problem different VLAN

Hello, i have a problem, LTM version 13.1.0.7. HA cluster "ACTIVE-ACTIVE".

I have a Virtual Server with IP 1.1.1.1%50(domain: ) Settings: Vlan 50

Self ip 1 LTM : 1.1.1.252%50 /24 Self ip 2 LTM : 1.1.1.253%50 /24 Self ip 1/2 LTM( FLOAT) : 1.1.1.254%50 /24

AutoMap Enbale

pool "test" with nodes:

1.1.1.2%50

1.1.1.3%50

Also i have iRule:

when HTTP_REQUEST {

if { [HTTP::uri] starts_with "/test2" } {

    use pool "test2"

} else {

use pool test

}

}

test2 pool:

1.1.1.4%50

1.1.1.5%50

It's working fine!

But if i have a pool with a different VLAN in Irule, it doesn't not work!

Settings VLAN 51:

Self ip 1 LTM : 1.1.2.252%51 /24 Self ip 2 LTM : 1.1.2.253%51 /24 Self ip 1/2 LTM( FLOAT) : 1.1.2.254%51 /24

Pool test3:

1.1.2.1%51

1.1.2.2%51

Irule example:

when HTTP_REQUEST {

if { [HTTP::uri] starts_with "/test3" } {

    use pool "test3"

} else {

use pool test3

}

}
