利用vrrp协议及单臂路由实现vlan间高可用性通讯

单臂路由实现高可用性vlan间通讯

实验背景:

位于同于同于网络中的多台机器在不同的vlan之间

实验目的:

通过单臂路由实现vlan间高可用性vlan通讯

实验原理:

为了实现vlan之间通讯的高可用性及稳定性,本次试验才用双设备实现,及两组设备互为备份,又各有分工,实现vlan10通讯时路由器ar1和交换机lsw1为主设备ar2和lsw2为备份设备,当主设备发生故障造成通讯失败时备份设备开始启用,继续保证vlan通讯正常进行,当主设备修复之后备份设备又保持断开不工作状态,同理ar2和lsw2为vlan20 通讯的主设备,原理同上.

主要协议:vrrp协议

实验简述:

本次试验共需要路由器两台,交换机两台,pc  四台, ar1的 eth0/0/0接口划分为两个子接口eth0/0/0.10和eth0/0/0.20,其中 eth0/0/0.10 的ip 地址:192.168.10.1 255.255.255.0 vlan10 优先级为120,eth0/0/0.20的ip 192.168.20.1 255.255.255.0  vlan 20 优先级为100

ar2的 eth0/0/0接口划分为两个子接口eth0/0/0.10和eth0/0/0.20,其中 eth0/0/0.10 的ip 地址:192.168.10.2 255.255.255.0 vlan10 优先级为100,eth0/0/0.20的ip 192.168.20.2 255.255.255.0  vlan 20 优先级为120,路由器与交换机之间以及交换机和交换机之间为 trunk链路
