Спасибо всем большое за помошь -
я тестирую так , беру прописую с 2 х сторон :cisco 7204
interface Vlan502
ip address 192.168.1.1 255.255.255.0
*****
ip route 192.168.2.0 255.255.255.0 192.168.1.2
и с
cisco 3560
interface Vlan502
ip address 192.168.1.2 255.255.255.0
******
ip route 192.168.2.0 255.255.255.0 192.168.1.1
Тем самым делая петлю
ДАлее с Unix машины начинаю запускать ICMP запросы на 192.168.2.1 (штук 10 -20)
ping -f -s 1500 -ь 254 192.168.2.1 > /dev/null &
