GTM iRule to return CNAMEs based on LB_SELECTED

Hello,

Just want to make sure my iRule beneath my signature is correct. My intent:

1. If the GTM chooses server 1.1.1.1, return cname "foo1.bar.com".
2. If the GTM chooses server 2.2.2.2, return cname "foo2.bar.com"
3. If the GTM chooses another server not equal to 1.1.1.1 or 2.2.2.2, return that server's IP address directly to the LDNS client.

Will this work?

Thanks, Jim

when LB_SELECTED {

    if {[LB::server addr] equals "1.1.1.1"} {
        persist enable
        cname "foo1.bar.com"
    }
    elseif {[LB::server addr] equals "2.2.2.2"} {
        persist enable
        cname "foo2.bar.com"
    }
}
