Virtual Server Ordering

No, it will handle traffic from most-specific to least-specific. So 192.168.1.1:80 will get port 80 traffic before 192.168.1.1:0 will, and both would process traffic before a wildcard 0.0.0.0 virtual server.

If I created two virtual servers which have a same destination (Let say 192.168.1.0/24) but have a different type (Let say Performance (Layer 4) and Forwarding (IP)), how does BIGIP handle the traffic to 192.168.1.0/24.

SOL6459 goes over some examples of virtual server precedence:

A virtual server must be unique across four properties: IP address, port, protocol and VLAN. So you couldn't configure two virtual servers with identical destinations using the same protocol on the same VLAN. You should get an error when trying to configure a Perf Layer4 VS if you already have a Forwarding IP VIP configured on the same destination network/subnet and VLAN.

 

 

I was able to test and create a Forwarding (Layer 2) VS and Performance (Layer 4) VS on the same destination network/subnet. I didn't expect this to work. Anyone know why this is possible?

 

 

Thanks,

I wouldn't have expected that to work either. If they are enabled on the same vlans, I would expect that to throw an error. Can you send traffic to it and see which, if any, shows traffic statistics?
