gtm match source send to member in DC

Been working in this GTM irule all day put cant get it to work. This is for a GTM with one member in each DC. Basically need to check source IP and WideIP member status, if up then send to member in correct DC.

 

when DNS_REQUEST { Match on DAServer Networks if { [IP::addr [IP::client_addr] equals 192.168.163.0/24] ) { Check status of member Mobilemail-IT is UP if { [LB::status vs 192.168.163.39] eq "up" } { host 192.168.163.39 } } else { Match on DFServer Networks if { [IP::addr [IP::client_addr] equals 192.168.204.0/24] ) { Check status of Mobilemail-DF is UP if { [LB::status vs 192.168.204.39] eq "up" } { host 192.168.204.39 } } if both are down send to BV else { host 192.168.204.100 }

 

} }

    How are you troubleshooting ? Were you able to use log statements within the iRule to make sure the client IP and the pool member IP are logged after each decision ?

    Check the syntax - there seems to be brackets like ) in the iRule for some reason. You can also use "and" within the iRule:

    if { ([IP::addr [IP::client_addr] equals 192.168.163.0/24]) and ([LB::status vs 192.168.163.39] eq "up") } {

    I got it working, re did the irule using switch command helped to clean the syntax, using this format was clean and easier to work with...switch [IP::remote_addr] {

     

    "10.10.10.0/24 " { if { [LB::status vs TeasA] eq "up" } {
