hclp第三次 - 技术栈

题目：

需求：

1、PC1 和 PC2 处于不同的 VLAN

2、SW1 和 SW2 是终端设备的网关所在地

3、SW1 作为 VLAN 10 的主网关；SW2 作为 VLAN 20 的主网关

4、实现负载分担效果，且 SW1 和 SW2 互为备份

分析

1.LSW1 和 LSW2 是终端设备的网关所在地配置 LSW1、LSW2 为三层交换机，创建 VLANIF 接口作为网关

2利用 VRRP 多组技术实现负载分担，让两台设备同时工作，提高设备利用率。

出口路由器配置静态路由，保证内网与外部路由可达。

4.通过优先级控制 VRRP 主备关系，实现流量分担与冗余备份。
