实验目的:

配置多条ip route 0.0.0.0 0.0.0.0实现负载均衡。

实验拓扑:

 

ip route 0.0.0.0 0.0.0.0间负载均衡验证实验分析_ip route

配置:

R1:

interface FastEthernet0/0
 ip address 12.1.1.1 255.255.255.0
!
interface FastEthernet0/1
 ip address 13.1.1.1 255.255.255.0

!
ip route 4.4.4.0 255.255.255.0 12.1.1.2
ip route 4.4.4.0 255.255.255.0 13.1.1.3

R2:

interface FastEthernet0/0
 ip address 12.1.1.2 255.255.255.0
!
interface FastEthernet0/1
 ip address 10.1.1.2 255.255.255.0
!
ip route 0.0.0.0 0.0.0.0 FastEthernet0/1

R3:

interface FastEthernet0/0
 ip address 10.1.1.3 255.255.255.0
!
interface FastEthernet0/1
 ip address 13.1.1.3 255.255.255.0
!
ip route 0.0.0.0 0.0.0.0 FastEthernet0/0

R4:

interface Loopback0
 ip address 4.4.4.4 255.255.255.0
!
interface FastEthernet0/0
 ip address 10.1.1.4 255.255.255.0

ip route 0.0.0.0 0.0.0.0 FastEthernet0/0

说明:

负载均衡会受到CEF的影响,所以默认情况,可能不是你想要的结果。此实验要关闭R1的CEF.
