[inet-admins] bridging and routing over FR :(
Столкнулся с такой проблеммой, может кто наступал на похожее, подскажите...
Конфигурирование роутинга IP WAN и бриджинга IP LAN сети на маршрутизаторе
включенном в Inet и маршрутизатор корпоративной сети.
Центральный оффис:
Имеется cisco-2621 (IOS 12.0) подключенная по FR(Serial0/0.102) в Интернет.
На interface FastEthernet0/0 находится LAN локального Internet узла.
На interface FastEthernet0/1 находится office LAN на внутренних адресах.
Имеется еще один FR (Serial0/0.101) для связи с cisco-2509 в удаленном оффисе.
Удаленный оффис:
Имеется cisco-2509 (IOS 11.2) подключенная по FR(Serial0/0.101) к
центральному оффису. На interface Ethernet0 находится LAN удаленного оффиса
на внутренних адресах той же сети, что и в центральном оффисе.
Задача: Обеспечить бриджинг между локальными сетями оффисов и их доступ
к сегменту локального узла Интернет.
Проблема: Не проходит IP (ping) от локального маршрутизатора в LAN интерфейс
удаленного маршрутизатора с адресом сети для бриджинга.
