маршрутов
(Filtering with Route-Map)
В данном примере мы перераспределяем в EIGRP два адреса, которым присваиваем им соответствующие метки, в дальнейшем по меткам их можно будет перераспределять.
r1(config)#route-map conn_eigrp permit 10
r1(config-route-map)#match interface loopback10
r1(config-route-map)#set tag 10
r1(config-route-map)#route-map conn_eigrp permit 20
r1(config-route-map)#match interface loopback100
r1(config-route-map)#set tag 100
r1(config-route-map)#exit
r1(config)#router eigrp 1
r1(config-router)#redistribute connected route-map conn_eigrp
Первая команда показывает, что данные маршруты пришли как внешние, две другие присвоенные метки. Проверка осуществляется командами:

(Filtering with Administrative Distance)
В данном примере мы устанавливаем для адреса 10.1.1.1 максимальную административную дистанцию и делаем его не достижимым.
