NimbostratusIsp link test on LTM
Hi,
I have two SMTP servers and two ISP.
Each SMTP server is using a different ISP link.
I would like to load balance SMTP (outbond) between these two servers. The problem is how to tell LTM not...
Hi,
if you can ping the gateway for every ISP links, this should be easy.
Just create an icmp monitor for every ISP link and add in the field "Alias Address" the gateway for this link.
Then you can assign the isp specific monitors to the specific node. If the ping fails, the ltm will disable the node.
If the ltm cannot ping the gateway, you have to move the monitoring for the ISP links you to your smtp servers. You can create a cronjob, which monitors the ISP links and if a link fails, just disable the smtp server. Then the LTM will notice a failed node and will take down it.
