bugcy013 commented 7 years ago

Hi Guys,

When we try to run fault_tolerant_router, I am getting some syntax issue with ip route command. I am trying to replicate fault tolerant router in my local setup. I am getting is error.

base machine:  Linux mint = 18
Kernel Version = 4.4.0-21 generic

Please let us know which base machine you guys tested, so that I can try to replicate.

console prints for your reference purpose

I get the same but everything still seems to work - kinda... Would love to hear developer feedback on this.
