STP+VRRP综合实验

一、实验拓扑

二、实验需求

1,内网Ip地址使用172.16.0.0/16分配
2,sw1和SW2之间互为备份
3, VRRP/STP/VLAN/Eth-trunk均使用
4,所有Pc均通过DHCP获取IP地址
5,ISP只能配置IP地址
6,所有电脑可以正常访问IsP路由器环回

三、实验分析

1、二层设备上创建VLAN并划分端口，下面配置access口，交换机之间配置trunk链路，SW1和SW2之间配置Eth-trunk聚合
2、配置三层交换机，配置vlan接口，SW1 配置vlanif10,SW2配置vlanif20，R1连接内网和ISP接口，iSP配置IP地址和环回IP
3、指定根桥，sw1为vlan10的主根桥，sw2为vlan20的主根桥，之后pc接入端口启用边缘保护
4、在SW1和SW2上面配置vrrp
5、配置DHCP服务，在SW1和SW2的vlanif2\3上面激活DHCP，sw1、sw2 、r1启用ospf
7、所有交换机配置MSTP，配置NAT（IPv4访问ISP， IPv6环回）
