маршрутизация eigrp,

slavura, 10-Сен-07, 18:02 [смотреть все]

Помогите разобраться с маршрутизацией eigrp.
Есть сеть из нескольких филиалов, на маршрутизаторах Cisco (в основном 871 и 1751)... Между ними настроены IPSec-тунели и настроена eigrp-маршрутизация... Все вроде как работает, кроме одного филиала. Там маршрутизатор не получает статичесские маршруты, рассылаемые другими маршрутизаторами... Вот кусок конфига (на всех остальных маршрутизаторах конфиги аналогичные):

В данном примере я не вижу статических маршрутов, кроме default. При этом вижу маршруты, полученные по EIGRP от других. Если на других маршрутизаторах тоже только дефолты, то надо написать в router eigrp команды default-information allowed {in|out}

Статичесские маршруты есть на других маршрутизаторах, по идеи, если использовать redistribute static и redistribute connected, то должны рассылаться и статичесские маршруты по eigrp. Вот что имеется в таблице маршрутизации на другом роутере:
