HCNP综合实验
综合实验HCNP小型网络
实验拓扑
实验需求
- 按照拓扑搭建网络环境,网络拓扑分为总部、分部二,设备IP地址见IP地址规划表。
- 总部4台交换机采用MSTP协议防止环路及实现链路冗余。其中VLAN10的主根为SW1,VLAN20的主根为SW2。
- SW1与SW2之间运行VRRP协议,PC的的网关在虚拟路由器上。要求VLAN10业务由SW1转发,VLAN20业务由SW2转发。
- 总部与分部二都运行OSPF协议,总部属于AREA 0,分部二属于AREA 1。为了确保安全性,总部与分部二之间链路需要启用接口认证,认证口令为SPOTO。
- 总部AREA 0通过OSPF学习到默认路由。
- 总部与分部二之间属于不同的自治域,要求启用BGP协议互联。
- 分部二内的三台路由器采用环回口建立IBGP邻居, 并在R4上宣告Loopback1和Loopback2。
- 通过修改MED的方式,实现R1前往16.10.1的路由优选R2,R1前往172.16.20.1的路由优选R3。
- R5为模拟运营商设备,总部有上公网的需求,但仅允许VLAN10的设备访问,在R1进行NAT配置,采用PC1、PC2 ping R5进行测试。
