iRule: Direct request to specific server, but you use pool if that server is down not working.

ok, let me try that and have end user do the testing.

So we went with the following in a test environment and it worked. I would prefer if its up to do something, instead of if its not up do something in your example. Only because our team is new to iRules and think my way is a little bit more clear for the casual reader. That being said your formatting and how to check the status made the difference. Thank you so much. As I type this I do see how your way is a better choice.If member is down, immediately go to the pool, instead of checking the rest of the iRule then defaulting to the available pool.

# Force A.A.A.A to go to 1.1.1.1

# Force B.B.B.B to go to 2.2.2.2

# Unless destination node is down

# All other clients will use pool

when CLIENT_ACCEPTED {

  if { ([LB::status pool SERVICE_60006_pool_pool member 1.1.1.1 60006] eq "up") && [IP::addr [IP::client_addr] equals A.A.A.A] }

   { node 1.1.1.1 60006}

  elseif { ([LB::status pool SERVICE_60006_pool_pool member 2.2.2.2 60006] eq "up") && [IP::addr [IP::client_addr] equals B.B.B.B] }

   { node 2.2.2.2 60006}  

  else {pool SERVICE_60006_pool_pool}

}

I'm happy to help. Your way to make if statement posibble too, of course, just a matter of taste:)
