2.SW1 和 SW2 之间利用三条裸光缆实现互通，其中一条裸光缆承载三层 IP 业务、一条裸光缆承载 VPN 业务、一条裸光缆承载二层业务。
用相关技术分别实现财务 1 段、财务 2 段业务路由表与其它业务路由表隔离，财务业务 VPN 实例名称为 Finance，RD 为 1:1。承载二层业务的只有一条裸光缆通道，配置相关技术，方便后续链路扩容与冗余备份，编号为 1，用 LACP 协议，SW1 为 active，SW2 为 passive；采用目的、源 IP 进行实现流量负载分担。

3.为方便后续验证与测试，SW3 的 E1/0/22 连接其他合适设备的一个接口，配置为 trunk，允许 Vlan31-34、110、120 通过。
这里可以连接到SW1的1/0/1口以测试ip dhcp snooping
4.将 SW3 模拟办事处交换机，实现与集团其它业务路由表隔离，办事处路由表 VPN 实例名称为 Office，RD 为 1:1。将 SW3 模拟为 Internet交换机，实现与集团其它业务路由表隔离，Internet 路由表 VPN 实例名称为 Internet，RD 为 2:2。

monitor session 1 source interface Ethernet1/0/19 rx
monitor session 1 destination interface Ethernet1/0/1
!
7.SW1 和 SW2 E1/0/21-28 启用单向链路故障检测，当发生该故障时，端口标记为 errdisable 状态，自动关闭端口，经过 1 分钟后，端口自动重启；发送 Hello 报文时间间隔为 15s；

(三)路由调试
1.配置所有设备主机名，名称见“网络拓扑”。启用所有设备的 ssh 服务，用户名和明文密码均为 admin；配置所有设备 ssh 连接超时为 9分钟，console 连接超时为 30 分钟。
SW
exec-timeout 30 0
!
ssh-server enable
ssh-server timeout 540
RT
line console 0
exec-timeout 1800
!
!
ip sshd timeout 540
ip sshd enable
!
FW
ssh timeout 9
console timeout 30
2.配置所有设备的时区为 GMT+08:00。调整 SW1 时间为实际时间，SW1配置为 ntp server，其他设备为 ntp client，请求报文时间间隔 1分钟，用 SW1 Loopback1 IPv6 地址作为 ntp server 地址。
SW1
clock timezone GMT add 8 0
!
ntp enable
ntp-service refclock-master 1
!
SW2-3;AC
clock timezone GMT add 8 0
!

(五)安全维护
1.FW1 配置 IPv4 NAT，id 为 1，实现集团产品 1 段 IPv4 访问 InternetIPv4，转换 ip/mask 为 200.200.200.16/28，保证每一个源 ip 产生的所有会话将被映射到同一个固定的 IP 地址。
2.FW1 配置 NAT64，id 为 2，实现集团产品 1 段 IPv6 访问 InternetIPv4，转换为出接口 IP，IPv4 转 IPv6 地址前缀为 64:ff9b::/96。3.FW1 和 FW2 策略默认动作为拒绝，FW1 允许 集团产品 1 段 IPv4 和IPv6 访问 Internet 任意服务。
### 3.FW1 和 FW2 策略默认动作为拒绝，FW1 允许 集团产品 1 段 IPv4 和IPv6 访问 Internet 任意服务。<-防火墻默認動作為拒絕->
4.FW2 允许办事处产品 IPv4 访问集团产品 1 段 https 服务，允许集团产品 1 段和产品 2 段访问 SW3 模拟办事处 Loopback2 IPv4、FW2Loopback1 IPv4、办事处产品 IPv4。
5.FW1 与 RT2 之间用 Internet 互联地址建立 GRE Over IPSec VPN，实现 Loopback4 之间的加密访问。RT2 的 ACL 名称为 ACL-VPN，transform-set 名称为 SET-1，crypto map 名称为 MAP-1。FW1 的isakmp proposal 名称为 P-1，isakmp peer 名称为 PEER-1，ipsecproposal 名称为 P-2，tunnel ipsec 名称为 IPSEC-1，tunnel gre 名称为 GRE-1。
