44.3 ECMP Typical Example

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.

44.3.1 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
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

Explanation
Set load-balance for switch, it takes effect for
port-group and ECMP function at the same time.
