网络拓扑图及 IP 地址表：

1.网络拓扑图

SW1:

Interface Ethernet1/0/22
switchport mode trunk //设置端口模式为trunk
switchport trunk allowed vlan 11-15 //只允许vlan11-15通过

SW2:

Interface Ethernet1/0/22
switchport mode trunk
switchport trunk allowed vlan 21-25

(二)交换配置

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。

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。

SW3：

注：sw3的e1/0/22可以连接到SW1，SW2合适的口测试，也可以在端口里设置LOOKBACK

5.SW1 配置 SNMP，引擎 id 分别为 1000；创建组 GroupSkills，采用最高安全级别，配置组的读、写视图分别为：Skills_R、Skills_W；12 / 35 创建认证用户为 UserSkills，采用 aes 算法进行加密，密钥为 Key- 1122，哈希算法为 sha，密钥为 Key-1122；当设备有异常时，需要用本地的环回地址 Loopback1 发送 v3 Trap 消息至集团网管服务器 10.4.15.120、2001:10:4:15::120，采用最高安全级别；当法务部门的用户端口发生 updown 事件时禁止发送 trap 消息至上述集团网管服务器。

SW1:

snmp-server enable //启动snmp 功能

snmp-server engineid 1000 //配置引擎 id 为 1000

snmp-server user UserSkills GroupSkills authPriv aes b693dfa497e63a03e2b4a1d3709b0723 auth sha b693dfa497e63a03e2b4a1d3709b0723f62da73a //创建用户认证，用户名后跟组名，这里密码Key-1122是因为加密过的，密码配置时换成题目要求的即可

snmp-server group GroupSkills authpriv read Skills_R write Skills_W //创建组，与读写视图

snmp-server host 2001:10:4:15::120 v3 authpriv UserSkills //设置接收端（网管服务器地址，配置最高安全级别）

snmp-server host 10.4.15.120 v3 authpriv UserSkills

snmp-server trap-source 10.4.1.1 //配置接受端地址
snmp-server trap-source 2001:10:4:1::1

snmp-server host 10.4.15.120 v3 authpriv UserSkills
snmp-server enable traps //启动snmp trap 功能

6.对 SW1 与 FW1 互连流量镜像到 SW1 E1/0/1，会话列表为 1。

SW1

monitor session 1 source interface Ethernet1/0/19 both

//配置源端口，可以不用加both,默认有

monitor session 1 destination interface Ethernet1/0/1

//配置目的端口

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；

SW1:

uldp enable

//启动单向链路故障检测

uldp recovery-time 60

//设置重启时间

uldp hello-interval 15

//设置hello报文时间间隔

uldp aggressive-mode

//发生故障时，相应端口标记为 errdisable 状态

int ethernet 1/0/21-28

uldp enable

uldp aggressive-mode

//配置检测相应的端口与标记

SW2:同上

8.SW1 和 SW2 所有端口启用链路层发现协议，更新报文发送时间间隔为 20s，老化时间乘法器值为 5，Trap 报文发送间隔为 10s，配置三条裸光缆端口使能 Trap 功能。

lldp enable

启动lldp功能

lldp msgTxHold 5

配置老化时间乘法器

lldp tx-interval 20

配置更新报文发送时间间隔

lldp notification interval 10

配置trap报文发送时间间隔

int ethernet 1/0/1-28

lldp enable

所有端口启用lldp协议

int ethernet 1/0/22-24

lldp trap enable

三条裸光缆端口使能 Trap 功能

(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。

注：所有设备主机名，hostname+主机名，所有设备默认用户名和密码为admin,不用配置

SW1-3 AC1:

ssh-server enable

启用ssh功能

ssh-server timeout 540

配置ssh连接超时为九分钟，交换机;AC及RT默认以秒为单位

exec-timeout 30

配置console连接超时为30分钟，交换机;AC默认以分钟为单位

RT1-2:

ip sshd enable

启用ssh功能

ip sshd timeout 540

配置ssh连接超时为九分钟

line vty 0

exec-timeout 1800

进入虚拟终端配置,配置console连接超时为30分钟，RT默认以秒为单位

FW1-2:

admin user admin

access ssh

password Key-1122

配置ssh功能并设置密码，输入 password Key-1122 后，会提示  Please input the old password: ，需要输入原密码admin即可修改

ssh timeout 9

配置ssh连接超时为九分钟，防火墙默认以分钟为单位

console timeout 30

配置console连接超时为30分钟，防火墙默认以分钟为单位

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
设置设备时区

ntp enable
启动ntp功能

ntp-service refclock-master 1
设置SW1为ntp 服务器地址

SW2-SW3-AC1:

clock timezone GMT add 8 0

ntp enable

ntp server 2001:10:4:1::1

使用SW1 LOOPBACK1 的服务器地址

ntp syn-interval 60

配置请求报文时间间隔为1 分钟，交换机;AC及RT默认以秒为单位

RT1-2:

time-zone GMT 8 0

配置时区

ntp server 2001:10:4:1::1

使用SW1 LOOPBACK1 的服务器地址

ntp query-interval 60

配置请求报文时间间隔为1分钟

FW1-2

clock zone GMT 8 0

设置时区

ntp enable

启动ntp功能

ntp server 2001:10:4:1::1

使用SW1 LOOPBACK1 的服务器地址

ntp query-interval 1

配置请求报文时间间隔为1 分钟，防火墙默认以分钟为单位

3.配置接口 IPv4 地址和 IPv6 地址，互联接口 IPv6 地址用本地链路地址。FW1 和 FW2 接口仅启用 ping 功能以及 Loopback1 的 ssh 能。

注：交换机与AC默认开启ipv6功能，不用配置，互联接口是指直连接口;
因交换机与AC默认开启IPv6功能，所以只用在路由器，防火墙上配置

4.SW2 配置 DHCPv4 和 DHCPv6，分别为 Vlan11、Vlan21、Vlan130、 Vlan140、Vlan150 分配地址。DHCPv4 地址池名称分别为 PC1、PC2、 AP1、POOLv4-VLAN11、POOLv4-VLAN21、POOLv4-VLAN130、POOLv4- VLAN140、POOLv4-VLAN150，排除网关，DNS 为 10.4.210.101 和 10.4.220.101。DHCPv6 地址池名称分别为 POOLv6-VLAN11、POOLv6- VLAN21、POOLv6-VLAN130、POOLv6-VLAN140、POOLv6-VLAN150，DHCPv6 地址池用网络前缀表示,排除网关，DNS 为 2400:3200::1。PC1 保留地址 10.4.11.9（DHCPv4 地址池名称为 PC1）和 2001:10:4:11::9，PC2 保留地址10.4.21.9（DHCPv4 地址池名称为 PC2）和2001:10:4:21::9， AP1 保留地址 10.4.130.9 （ DHCPv4 地址池名称为 AP1 ）和 2001:10:4:130::9。SW1、AC1 中继地址为 SW2 Loopback1 地址。SW1 启用 DHCPv4 和 DHCPv6 snooping 功能，如果 E1/0/1 连接 DHCPv4 服务器，则关闭端口，恢复时间为 10 分钟。

SW2:
启动ipv4-dhcp功能，配置IPV4地址池，保留地址，排除网关

创建相应前缀列表和调用route-map

修改 ospf cost 为 100，实现 SW1 分别与 RT2、FW2 之间 IPv4 和 IPv6

互访流量优先通过 SW1-SW2-RT1 链路转发，SW2 访问 Internet IPv4

和 IPv6 流量优先通过 SW2-SW1-FW1 链路转发。

RT1:
!
interface GigaEthernet0/1

 ipv6 ospf cost 100 
!
Fw1:

最简单的方法是RT1与FW1的直连端口增加cost值实现优先选路

6.RT1 串行链路、RT2 串行链路、FW1、AC1 之间分别运行 RIP 和 RIPng 协议，分别发布 Loopback2 地址路由（FW1 的 RIPng 发布路由时用接口名称）。RT1 配置 offset 值为 3 的路由策略，实现 RT1/S1/0- RT2/S1/1 为主链路，RT1/S1/1-RT2/S1/0 为备份链路，IPv4 的 ACL 名称为 ACL-RIP-IPv4，IPv6 的 ACL 名称为 ACL-RIP-IPv6。RT1 的 S1/0 与 RT2 的 S1/1 之间采用 chap 双向认证，用户名为对端设备名称，密码为 Key-1122。

RT1：
ip access-list standard ACL-RIP-IPv4
 permit any  sequence 10
!
ipv6 access-list ACL-RIP-IPv6
 permit ipv6 any any sequence 10
!
创建ipv4 v6访问控制列表，允许所有路由通过

router rip 1 
 offset Serial1/1 in ACL-RIP-IPv4 3 
 offset Serial1/1 out ACL-RIP-IPv4 3

7.RT1 以太链路（物理速率为 2048000）、RT2 以太链路、FW1 之间运行 ISIS 协议，instance 1，实现 Loopback3 之间 IPv4 互通和 IPv6 互通。RT1、RT2、FW1 的 NET 分别为 10.0000.0000.0005.00、 10.0000.0000.0006.00 、 10.0000.0000.0007.00 ，路由器类型是 Level-2，互联接口网络类型为点到点。

SW1 和 SW2 之间财务通过 Loopback2 建立 IPv4 和 IPv6 BGP 邻居。SW1 和SW2的Loopback2 IPv4互通采用静态路由；IPv6互通采用OSPFv3， process 2，area 2。

SW1:
配置LOOPBACK2静态路由互通：ip route vrf  Finance 10.4.2.2/32 10.4.255.2  
//10.4.2.2/32 是目标地址SW2的loopback2地址，10.4.255.2是下一跳地址，对端vpn 1/0/24 的地址

9.利用 BGP MPLS VPN 技术，RT1 与 RT2 以太链路间运行多协议标签交换、标签分发协议。RT1 与 RT2 间创建财务 VPN 实例，名称为 Finance， RT1 的 RD 值为 1:1，export rt 值为 1:2，import rt 值为 2:1；RT2 的 RD 值为 2:2。通过两端 Loopback1 建立 VPN 邻居，分别实现两端 Loopback5 IPv4 互通和 IPv6 互通。

RT1:
mpls ip  
全局启用
mpls ldp router-id 10.4.5.1
配置Ldp路由标识 

interface GigaEthernet0/0
 mpls ip
接口启用
 mpls ldp enable
配置Ldp接口路由标识
!
ip vrf Finance
 rd 1:1
 route-target export 1:2
(给出去的流量打上标签） 
因为1:2是出口标签，所以RT2的import为1:2，接受RT1发出的的标签
 route-target import 2:1
（接受进入的标签流量） 
因为2:1是进入标签，所以RT2的export为2:1，发出2:1标签是RT1接收
!
ipv6 vrf Finance
 rd 1:1
 route-target import 2:1
 route-target export 1:2
!
配置ipv4与ipv6实例

验证：

可以看到已经通过LOOPBACK1建立了vpn邻居

可以看到loopback5已经在bgp vrf v4和v6中互通

10.RT2 配置 IPv4 NAT，ACL 名称为 ACL-NAT，实现 AC1 IPv4 产品用 RT2 外网接口 IPv4 地址访问 Internet。RT2 配置 NAT64，ACL 名称为 ACL-NAT64，实现 AC1 IPv6 产品用 RT2 外网接口 IPv4 地址访问 Internet，IPv4 地址转 IPv6 地址前缀为 64:ff9b::/96。

RT2:
ip route default 200.200.200.5 
!
//设置默认路由将所有未明确指定目的地的流量（即默认流量）转发到指定的下一跳地址，以便能成功访问外网
ip access-list standard ACL-NAT

 //约定NAT4转换规则
!
ipv6 access-list ACL-NAT64

 //约定nat64 转换规则

interface GigaEthernet0/1
 ip nat inside
//对内接口

//接口启动ipv6转换

!

AC1上用产品ping外网成功，RT2上显示转换命中成功

AC1上用ipv6产品ping外网成功,ipv6转换成功

(四)无线部署

1.AC1 与 AP1 相连接口只允许 Vlan140 和 Vlan150 通过。AC1 Loopback1 IPv4 和 IPv6 地址分别作为 AC1 的 IPv4 和 IPv6 管理地址。AP 二层自动注册，AP 采用 MAC 地址认证。配置 2 个 ssid，分别为 SKILLS-2.4G 和 SKILLS-5G。SKILLS-2.4G 对应 Vlan140，用 Network140 和 radio1（profile 1, mode n-only-g）,用户接入无线网络时需要采用基于 WPA-personal 加密方式，密码为 Key-1122，用第一个可用 VAP 发送 2.4G 信号。SKILLS-5G 对应 Vlan150，用 Network 150和 radio2（profile 1, mode n-only-a），不需要认证，隐藏 ssid，SKILLS-5G 用倒数第一个可用 VAP 发送 5G 信号。

AC1:
 wireless 
进入ap配置模式
 enable

取消动态分配
 ap authentication mac
开启mac认证模式
 ap database 00-03-0f-d9-cd-c0

验证：

可以看到ap已经上线

(五)安全维护（本题共 5 分）

说明：按照 IP 地址从小到大的顺序用“IP/mask”表示，IPv4 Any

地址用 0.0.0.0/0，IPv6 Any 地址用::/0，禁止使用地址条目。

1.FW1 配置 IPv4 NAT，id 为 1，实现集团产品 1 段 IPv4 访问 Internet IPv4，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 Internet IPv4，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。

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、FW2 Loopback1 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，ipsec proposal 名称为 P-2，tunnel ipsec 名称为 IPSEC-1，tunnel gre 名称为 GRE-1。

SW3:
ip route  vrf  Office 0.0.0.0/0 200.200.200.6 
ip route  vrf  Office 0.0.0.0/0 200.200.200.2
//转发实例达到互联互通
RT1:
因为前面nat转换配过默认路由，所以可以不用配默认路由

!
配置ACL-VPN，使特定流量通过

crypto map MAP-1 1 ipsec-isakmp

 set peer 200.200.200.2
 set transform-set SET-1
!
//创建加密图

interface GigaEthernet0/2
 crypto map MAP-1
!
//调用加密图

FW1:
 ip route  0.0.0.0/0 200.200.200.1
