eNSP虚拟局域网VLAN

虚拟局域⽹VLAN技术+DHCP+OSPF

实验拓扑

实验说明

交换机

S1：需要创建 vlan、配置 access 和 trunk 接⼝、并将相应接⼝加⼊对应 vlan3 中。S2：需要创建 vlan、配置 access 和 trunk 接⼝、并将相应接⼝加⼊对应 vlan9 中。

S3：需要创建 vlan、配置 access 和 trunk 接⼝、配置 vlanif 3 和 vlanif 9 接⼝及其 IP 地址，创建 vlan1002，并配置 vlanif 1002 接⼝及其 IP 地址 192.168.2.1/24。S4：需要创建vlan、配置access和trunk接⼝、配置vlanif 105接⼝及其IP地址，创建vlan1004，并配置 vlanif 1004 接⼝及其 IP 地址 192.168.4.1/24。

路由器

R1：配置各接⼝ IP 地址、配置 OSPF 协议。

R2：配置各接⼝ IP 地址、配置 OSPF 协议。
