Figure 4-5 the application environment of ECMP

As it is shown in the figure, the R1 connect to R2 and R3 with the interface address

100.1.1.1/24 and 100.1.2.1/24. The R2 and R3 connect to R1 with the interface address

100.1.1.2/24 and 100.1.2.2/24. The R4 connect to R2 and R3 with interface address

100.2.1.1/24 and 100.2.2.1/24. The R2 and R3 connect to R4 with the interface address

100.2.1.2/24, 100.2.2.2/24. The loopback address of R4 is 5.5.5.5/32.

4.4.3.1 Static Route Implements ECMP

R1(config)#ip route 5.5.5.5/32 100.1.1.2

R1(config)#ip route 5.5.5.5/32 100.1.2.2

On R1, show ip route, the following is displayed:

R1(config)#show ip route
