Для связности между loopback-интерфейсами маршрутизаторов R1 и R3 не требуется, чтобы на маршрутизаторе R2 был настроен BGP и присутствовали все маршруты в таблице маршрутизации. При увеличении MPLS-облака в размерах это становится заметным преимуществом использования технологии коммутации по меткам.

Ниже представлен вывод на консоль таблицы маршрутизации ECO-1.

ECO-1#sh ip route
Codes: K - kernel, C - connected, S - static, R - RIP, B - BGP
    O - OSPF, IA - OSPF inter area
    N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
    E1 - OSPF external type 1, E2 - OSPF external type 2
    i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
    * - candidate default
IP Route Table for VRF "default"
B    1.1.1.1/32 [20/0] via 11.0.0.1, e1, 19:33:53
B    3.3.3.3/32 [200/0] via 200.200.200.200 (recursive via 10.12.0.2 ), 19:33:40
C    10.12.0.0/16 is directly connected, e2
O    10.22.0.0/16 [110/20] via 10.12.0.2, e2, 19:34:09
C    11.0.0.0/16 is directly connected, e1
C    100.100.100.100/32 is directly connected, loopback.0
O    200.200.200.200/32 [110/30] via 10.12.0.2, e2, 19:33:56
