18.7 负载分担VRRP

1.R2配置VRRP

[R2]interface GigabitEthernet 0/0/1
[R2-GigabitEthernet0/0/1]vrrp vrid 1 virtual-ip 23.1.1.254
[R2-GigabitEthernet0/0/1]vrrp vrid 1 priority 120
[R2-GigabitEthernet0/0/1]vrrp vrid 2 virtual-ip 23.1.1.253
[R2-GigabitEthernet0/0/1]vrrp vrid 2 priority 100

2.R3配置VRRP

[R3]interface GigabitEthernet 0/0/0
[R3-GigabitEthernet0/0/0]vrrp vrid 1 virtual-ip 23.1.1.254
[R3-GigabitEthernet0/0/0]vrrp vrid 1 priority 100
[R3-GigabitEthernet0/0/0]vrrp vrid 2 virtual-ip 23.1.1.253
[R3-GigabitEthernet0/0/0]vrrp vrid 2 priority 120

3.配置静态路由

[R1]IP route-static 23.1.1.0 8 12.1.1.2
[R1]IP route-static 23.1.1.0 8 13.1.1.3
[R2]ip route-static 1.1.1.1 32 12.1.1.1
[R3]IP route-static 1.1.1.1 32 13.1.1.1

4.PC1路由跟踪

PC>tracert 1.1.1.1
traceroute to 1.1.1.1, 8 hops max
(ICMP), press Ctrl+C to stop
 1  23.1.1.254   78 ms  47 ms  31 ms
 2    *1.1.1.1   62 ms  31 ms

5.PC2路由跟踪

PC>tracert 1.1.1.1
traceroute to 1.1.1.1, 8 hops max
(ICMP), press Ctrl+C to stop
 1  23.1.1.253   93 ms  32 ms  46 ms
 2    *  *1.1.1.1   47 ms

6.端口R3的G0/0/0口，观察PC2连通性测试和路由跟踪

[R3]interface GigabitEthernet 0/0/0
PC2>ping 1.1.1.1 -t
From 1.1.1.1: bytes=32 seq=52 ttl=254 time=31 ms
From 1.1.1.1: bytes=32 seq=53 ttl=254 time=47 ms
Request timeout!
Request timeout!
From 1.1.1.1: bytes=32 seq=56 ttl=254 time=31 ms
From 1.1.1.1: bytes=32 seq=57 ttl=254 time=31 ms

PC2>tracert 1.1.1.1
traceroute to 1.1.1.1, 8 hops max
(ICMP), press Ctrl+C to stop
 1  23.1.1.254   31 ms  47 ms  31 ms
 2  1.1.1.1   47 ms  47 ms  47 ms
