      (Filtering with Prefix-List)

      В данном примере, мы запрещаем распространение адреса 10.4.4.4 и не пускаем на маршрутизатор r4 адрес 10.1.1.1.

      r4(config)#ip prefix-list r4_out seq 5 deny 10.4.4.4/32

      r4(config)#ip prefix-list r4_out seq 10 permit 0.0.0.0/0 le 32

      r4(config)# ip prefix-list r4_in seq 5 deny 10.1.1.1/32

      r4(config)# ip prefix-list r4_in seq 10 permit 0.0.0.0/0 le 32

      r4(config)#router eigrp 1

      r4(config-router)#distribute-list prefix r4_out out

      r4(config-router)#distribute-list prefix r4_in in

      В результате проверки, мы видим, что на маршрутизаторах r1 и r2 нет адреса 10.4.4.4, а адрес 10.1.1.1 присутствует на маршрутизаторе r2, а на r4 его нет.

      (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
