Are NTP and DNS traffic management type or not?

Hi Pete,

First of all, thanks for your reply and explanation. You confirmed my thoughts that NTP, DNS and services like that are are part of control plate, not the data plane, so related traffic should go via management interface, not via TMM switch ports.

I already had configured default routes for both TMM and Management interfaces. As I said NTP and DNS servers are located in other subnets, so to get packages there, f5 needs routing. So for example NTP server's IP hits default route 0.0.0.0 as there is no distinct route there and there are no direct path, but f5 chooses TMM default route. I guess it is because of route metric (as management metric has higher metric). I just don't understand why it is designed like that? I think it will be more logical, if programmatically control plane traffic will always choose management default route.

So, if I understand you correctly, you suggest me to create additional static routes via management interfaces, is that correct? I wonder what is the best practice from the Vendor's point of view? As static routes are considered as a poor design by Network Engineers, as it complicates troubleshooting.
