VRRP实验 2_dot1q vrrp vid 10-优快云博客

配置R1和R2的VRRP（虚拟路由冗余协议），创建VLAN 10和20，分配IP地址，并设置虚拟IP，以实现即使R1和SW1间线路故障，PC1和PC2仍能通过R2和R3保持与3.3.3.3的ping通。R3作为核心路由器，配置静态路由和Loopback接口，提供目标地址为3.3.3.3的可达性。

R1和R2上的g0/0/0配置接口
使得pc1和pc2能ping通3.3.3.3
是R1和SW1中间的线路故障，依然可以ping通3.3.3.3
在这里插入图片描述

路由器R1的配置

交换机SW1的配置

vlan batch 10 20
interface Ethernet0/0/1
 port link-type access
 port default vlan 10
#
interface Ethernet0/0/2
 port link-type access
 port default vlan 20
#
interface Ethernet0/0/3
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094
#
interface Ethernet0/0/4
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094
