iRule for replying host unreacheable if pool memebers down.

Hi rm,

 

 

ICMP is used to check if an IP address is available. A virtual server is an IP address and port combination. I don't think you could modify ICMP responses based on a single virtual server (or virtual server's pool's) status using an iRule.

 

 

I suppose you could use an iControl script to modify the virtual address state based on a pool's status.

 

 

What is polling the virtual server IP address? Could you have it do a service level check instead of using ICMP? ie, make a request to a specific IP:port instead of just the IP? If that was possible, then you could potentially use an iRule to send back a custom response based on the pool state.
