MSTP+VRRP组合实现S1和S2的（双交换）热备冗余及负载均衡

来源：互联网发布：日在校园知乎评价编辑：程序博客网时间：2024/06/05 16:41

一、前期准备：

1.所属部门vlan划分：

vlan2 zongcaiban172.16.2.253/24

vlan3 fenxiaobu172.16.3.253/24

vlan4 quyufazhan172.16.4.253/24

vlan5 shangpinbu172.16.5.253/24

vlan6 shichangbu172.16.6.253/24

vlan7 yingxiaoch172.16.7.253/24

vlan8 kuajinggyl172.16.8.253/24

vlan9 shequnyy172.16.9.253/24

vlan10 yunyingzc172.16.10.253/24

vlan11 qdcpjs172.16.11.253/24

vlan12 hdcpjs172.16.12.253/24

vlan13 kefu172.16.13.253/24

vlan14 wuliu172.16.14.253/24

vlan15 hr172.16.15.253/24

vlan16 fc172.16.16.253/24

vlan17 firewall172.16.17.253/24

vlan100 server172.16.100.253/24

各vlan网关为172.16.x.254且为vrrp组虚拟网关

2.实现功能

能够实现S1和S2的互相冗余和负载均衡

二、进行配置（如上图所示）

S2:

添加vlan和前面是一样的。Vlan的IP和s1是不能一样的。不然后面无法实现互为冗余。
