新华三杯2022全国赛解题

1.根据题目要求配置IP地址,修改设备名

2.L2W的vlan10绑定端口G1/0/1,vlan20绑定端口G1/0/1

3.交换机相连接口只放行vlan10 20，其余均不放行。

4.交换机与pc相连链路配置access模式。

5.Ce1 ce2 L2w之间配置stp，ce1 为vlan10的主根，ce2为vlan20的主根，域名为H3C

并在合适端口配置根保护，边缘端口，bpdu保护

6.CE1为vlan10主，CE2为vlan20。主Vrrp主根优先级为150，备用优先级为110，配置上行链路监视，当端口故障降低优先级50    

7.Ce1 ce2 与pe1连接的端口使用三层连接，

8.Pe1 pe2 pe3配置ospf 进程号1 lo0 地址为router-id 区域0，发布网段要求精确匹配

9.Ce1 ce2 配置ospf 进程号1 router-id为lo 0 地址 区域0 不允许协议报文发布到业务网段

10.Pe1 pe2 pe3 之间配置bgp 100，通过lo 0 建立ibgp， ce3 ce4配置bgp为300 通过直连端口建立ebgp

11.Ce5与pe2之间配置静态路由， pe3 与防火墙之间配置静态路由，internet与防火墙之间配置静态路由，防火墙配置区域 pe3为信任区域， internet为非信任区域

12.在防火墙配置nat，使server1可以访问internet

13.Pe1 pe2 pe3 配置mpls mpls-id为lo 0

14.Pc1 pc2 为server1 vpn1 ，pc3 server2 为vpn2

15. Ce1 ce2配置ipv6地址，配置ospfv3建立邻居，router-id是环回口地址
