zz016网络建设与运维正式赛卷（路由）

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。

SW1

ssh-server enable
ssh-server timeout 540
exec-timeout 30

SW2

ssh-server enable
ssh-server timeout 540
exec-timeout 30

SW3

ssh-server enable
ssh-server timeout 540
exec-timeout 30

RT1

ip sshd enable

line vty 0 4

exec-timeout 9

!

line console 0

exec-timeout 30

!

RT2

ip sshd enable 

line vty 0 4

exec-timeout 9

!

line console 0

exec-timeout 30

!

AC1

ssh-server enable 

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SW1Loopback1 IPv6 地址作为ntp server 地址。

SW1

clock timezone GMT add 8 0

clock set 时:分:秒 年:月:日

ntp enable

ntp-service refclock-master 1

SW2

3.SW2配置DHCPv4和DHCPv6，分别为总公司产品1段、总公司产品2段、分公司Vlan130、分公司Vlan140和分公司Vlan150分配地址。IPv4地址池名称分别为Poolv4-Vlan11、Poolv4-Vlan21、Poolv4-Vlan130、Poolv4-Vlan140、Poolv4-Vlan150，排除网关，DNS为10.1.210.101和10.1.220.101。IPv6地址池名称分别为Poolv6-Vlan11、Poolv6-Vlan21、Poolv6-Vlan130、Poolv6-Vlan140、Poolv6-Vlan150，IPv6地址池用网络前缀表示,排除网关，DNS为2400:3200::1。PC1保留地址10.1.11.9和2001:10:1:11::9，PC2保留地址10.1.21.9和2001:10:1:21::9，AP1保留地址10.1.130.9和2001:10:1:130::9。SW1、AC1中继地址为SW2 Loopback1地址，SW1启用DHCPv4和DHCPv6 snooping，如果E1/0/1连接dhcpv4服务器，则关闭该端口，恢复时间为10分钟。
