      EIGRP фильтрация с закрытой областью (Filtering with Stub Routing)

      Если маршрутизатор указан как Stub, то соседи не посылают ему запросы о маршрутах.

      r1(config)#route-map conn permit 10

      r1(config-route-map)#match interface loopback10 loopback100

      r1(config-route-map)#router eigrp 1

      r1(config-router)#redistribute connected route-map conn

      r1(config-router)#eigrp stub connected summary

      Проверка осуществляется командами:

      r4#show ip route eigrp | include EX
