Hi, i think that if you want to do load balance it's a question of switching process on the router (verify command like ip cef, ip route-cache etc.) Also what type of box do you have in your lab ? excuses my english michal

I also try to clear my neighbors a few times but I always got the same result I'm probably missing something but I can't figure it out. If you have any idea that could help me, that would be great.
