с

картой

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:

r4#show ip route eigrp
