CirrusIs there a traceroute equivalent in F5 like the format of ping -I <source ip> <destination ip>
Hi T0nyP,
Yes, this should work if the self IP is in route domain 0.

Hi T0nyP ,
F5 is Linux based so you can use normal Linux traceroute and all of its switches :
check below urls contain Traceroute with more and more details , you can use it with F5 bash shell :

I use it and it is very useful.

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>

Hey T0nyP,
The -g option is enabling soure-route IP option which is most likely banned from local or internet routers anyway...
Afaik there is no such option to overwrite the next-hop of the tracert command. Its always based on your local routing table. I might be wrong in this case tho...
Cheers, Kai
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.
> this is my explanation according to what I understood.
Kindly clarify more , I will follow up with you.
Regards
