Requesting assistance/clarification on traffic re-direction between pools

[Jay_PL]

Hi

Got a requirement in my organization to do the below. Is there any way we can do in F5 LTM?

URL: abc.net

Pool1: server1, server2

Pool2: server3, server4

All requests to the URL should go to Pool1 servers and when Pool1 servers are down, then traffic needs to go to pool2 servers.

Thank you

Jay

Hi Jay,

1. You can specify priority group by adding 4 members in a pool.

2. You can use iRule:

when CLIENT_ACCEPTED {
	if { [active_members Pool1] == 0 } {
		pool Pool2
	}
}
