select virtual server in iRule
Hi,
I want to the iRule to select another virtual server based on the selected memeber. The iRule shown below, I can see the log in ltm log but cannot use the vs1 or vs2...any idea? Thansk!
when LB_SELECTED {
if { [LB::server addr] eq "192.168.20.1" } {
virtual vs1
log local0. "vs1 selected"
}
elseif { [LB::server addr] eq "192.168.20.2" } {
virtual vs2
log local0. "vs2 selected"
}
}
Regards,
Ken

Hi,
which version of bigip do you have ?

As nmenant hinted at, you must be on 9.4.0 or higher to use the virtual command (Click here) to specify that the request should be sent to another virtual server.

I am having problem using the virtual command in an iRule. The LTM version is BIG-IP 9.4.3.when HTTP_REQUEST { log local0. "Request received, route to vs_01" virtual vs_01 }
The ltm log shows that vs_01 received the request but the tcpdump doesn't show any request being sent out of the LTM to the node in vs_01's default pool.
Is there any other configuration I am missing? Please help! Thank you!- Nicolas_Menantif vs 01 receive the traffic then it should be ok.
You should check your configuration of this VS, maybe you forgot something (SNAT or something else) - qqdixf5_74186I checked the configuration of vs_01. Everything looks good. I also tried to hit it with traffic and it works.
Strangely, if I hit the vs_01 first directly and then switch to the virtual server which has this rule applied to, the requests would go through for a short period of time. I tested it using both the browser and the iRule Editor generate traffic tool.
Any idea? Thanks!
