InterVlan маршрутизация на 3750, !*! Vladimir, 08-Июл-12, 16:26  [смотреть все]
Уважаемые, друзья. Прошу Вашей помощи.

Сеть(тестовая) состоит из 3ёх Cisco коммутаторов: C3750 (S1), C3550 (S2) и C2960 (S3), а также 3ёх маршрутизаторов: C2621 (R1), C1760 (R2), и C2610 (R3).

Схема: S3<-->S1<-->S2, на каждом коммутаторе висит роутер. R1 в Vlan10, R2 и R3 в Vlan20.
S1 выполняет функцию маршрутизации сетей с включённым процессом ip routing. Цель: чтобы рутеры пинговали друг друга.
