Hi,

 

There is no condition to check that the client IP is equal to "1.1.1.1" or "2.2.2.2" in your example.

 

You can try this code instead:

 

when HTTP_REQUEST {
    switch -glob [string tolower [HTTP::host]]{
        "abc.abc.com" {
            if { [IP::addr [IP::remote_addr] eq "1.1.1.1/32"] } { pool test_pool }
        }
        "xxx.yyy.com" {
            if { [IP::addr [IP::remote_addr] eq "2.2.2.2/32"] } { pool test_pool }
        }   
    }
}

And to help for debugging iRule you can use "log local0. " command, that will send the trace into /var/log/ltm log file. More information here: [https://devcentral.f5.com/articles/the101-irules-101-logging-amp-comments]
