Written iRule with help of if & elseif condition. Please check & let us know if any confusion.

   when DNS_REQUEST { 
    if { [IP::addr [IP::remote_addr] equals 192.168.163.0 mask 255.255.255.0]} {
        if {[LB::status vs 192.168.163.39 ] eq "up" } {
                host 192.168.163.39 } 
        else { 
            host 192.168.204.45 }
    elseif { [IP::addr [IP::remote_addr] equals 192.168.165.0 mask 255.255.255.0]} {
        if {[LB::status vs 192.168.163.39] eq "up" } { 
            host 192.168.163.39 }
        else { 
            host 192.168.204.45 }
    elseif { [IP::addr [IP::remote_addr] equals 192.168.204.0 mask 255.255.255.0]} { 
                    if { [LB::status vs 192.168.204.45] eq "up" } { 
            host 192.168.204.45 } 
        else { 
            host 192.168.163.39 }
                }
        }
        }

hope it will help

Still doesn't work, still getting close bracket errors.. I'm trying to use the switch command to create three separate checks on source IP's

 

when DNS_REQUEST { switch [IP::remote_addr] { "192.168.163.0/24 “ { if { [LB::status vs 192.168.163.39] eq "up" } {

 

host 192.168.163.39

 

} else { host 192.168.204.45

 

} } "192.168.165.0/24] " { if { [LB::status vs 192.168.163.39] eq "up" } {

 

host 192.168.163.39 } else { host 192.168.163.39 } } "192.168.204.0/24] " { if { [LB::status vs 192.168.204.45] eq "up" } {

 

host 192.168.204.45 } else { host 192.168.163.39 } }
