    Hi T0nyP,

    Yes, this should work if the self IP is in route domain 0. 

    Cheers, Kai

Thank you and really appreciate the feedback.

Just want to check. I don't have a linux as of the moment.

Would this run using below command?

traceroute -s <source ip> -g <gateway ip>  <destination ip or fqdn>

Hello T0nyP , 
No need to identify your gateway when performing traceroute , 
F5 does this path trace according to Routing table. 
> you can force your F5 appliance to check the path by using "traceroute -s " as you did. 

> I checked this option in F5 bash and it doesn’t work as you said , but there is no need to identify the gateway or next hop , F5 uses ( the gateway or next hop from the "forced source ip " subnet that you identified in your command ". 

> I want to say even if you specified the gateway , and overwrite the one which specified in f5 routing table/next hop , it is a wrong practise to use and it shouldn’t work.

Kindly clarify more , I will follow  up with you.
