实验：多组VRRP配置

实验：多组VRRP配置

实验目的

在网络中启用两个不同的VRRP组，最大限度保证了网络的冗余，避免网络单点出错引起用户无法访问网络

实验拓扑

配置要点

R1(config)#int f0/0

R1(config-if)#ip add 192.168.1.1 255.255.255.0

R1(config-if)#vrrp 1 ip 192.168.1.254

R1(config-if)#vrrp 1 priority 111

R1(config-if)#vrrp 1 preempt

R1(config-if)#int f0/0

R1(config-if)#vrrp 2 ip 192.168.1.253

R1(config-if)#vrrp 2 priority 222

R1(config-if)#vrrp 2 preempt

R2(config)#int f0/0

R2(config-if)#ip add 192.168.1.2 255.255.255.0

R2(config-if)#vrrp 1 ip 192.168.1.254

R2(config-if)#vrrp 1 pri 222

R2(config-if)#vrrp 1 preempt

R2(config-if)#vrrp 2 ip 192.168.1.253

R2(config-if)#vrrp 2 pri 111

R2(config-if)#vrrp 2 preempt

R3(config)#no ip routing

R3(config)#int f0/0

R3(config-if)#ip add 192.168.1.3 255.255.255.0

R3(config)#ip default-gateway 192.168.1.254

R6(config)#no ip routing

R6(config)#int f0/0

R6(config-if)#ip add 192.168.1.6 255.255.255.0

R6(config)#ip default-gateway 192.168.1.253

实验验证

R3#ping 1.1.1.1 repeat 400    在此过程中将R2 的f0/0 shutdown  然后在no shutdown

Type escape sequence to abort.

Sending 400, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!..!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Success rate is 99 percent (398/400), round-trip min/avg/max = 4/38/220 ms

将R2 的f0/0 shutdown

R3#traceroute 1.1.1.1

Type escape sequence to abort.

Tracing the route to 1.1.1.1

  1 192.168.1.1 52 msec 68 msec *

将R2 的f0/0  no shutdown

R3#traceroute 1.1.1.1

Type escape sequence to abort.

Tracing the route to 1.1.1.1

192.168.1.2 56 msec 64 msec

R6#ping 1.1.1.1 repeat 500  将R1 的f0/0  shutdown ,然后在 no shutdown

Type escape sequence to abort.

Sending 500, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! . . .!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!.!!!!

Success rate is 99 percent (496/500), round-trip min/avg/max = 4/38/124 ms
