Hi,

There is no way to get dynamic route information once system rebooted.

If you saved output of netstat -r anytime that will help you .

we can not do this, if you are having informations of old routing table there.

Are you have route / netstat -rn output in backup / memory? Then add approriate route rules to get that effect.

If you specify the requirement then it can also be done here.

You can't get it.Once machine is restarted the dynamic routing table will be lost.

Hi

Since you had mentioned that the system was rebooted don't see a chance of getting it back unless you had saved it somewhere.

It's gone off of that system, but other systems on the local segment may have similar tables. Run a netstat -r on a nearby system to get started.

Also check the closest gateway for its table. It will likely have more than you need, but may have what you're looking for.
