[LSW1]dhcp enable
[LSW1]int Vlanif 35 //为A配置IP地址
[LSW1-Vlanif35]dhcp select global
[LSW1]int Vlanif 36 //为B配置IP地址
[LSW1-Vlanif36]dhcp select global
[LSW1]ip pool poola //A的地址池

[LSW2-ip-pool-poolb]network 10.1.20.0 mask 24
[LSW2-ip-pool-poolb]gateway-list 10.1.20.6
（3）配置DHCP中继
[LSW3]dhcp enable
[LSW3-Vlanif10]dhcp select relay
[LSW3-Vlanif10]dhcp relay server-ip 10.1.5.3
[LSW3-Vlanif10]dhcp relay server-ip 10.1.45.4
[LSW4]dhcp enable
[LSW4]int Vlanif 20
[LSW4-Vlanif20]dhcp select relay
[LSW4-Vlanif20]dhcp relay server-ip 10.1.6.4
[LSW4-Vlanif20]dhcp relay server-ip 10.1.36.3 -
在出口路由器配置NAT
（1）在AR1上配置NAT
[AR1]nat address-group 1 20.1.1.4 20.1.1.10
[AR1]acl 2000
[AR1-acl-basic-2000]rule permit source 10.1.10.0 0.0.0.255
[AR1-GigabitEthernet0/0/1]nat outbound 2000 address-group 1
（2）在AR2上配置NAT
[AR2]nat address-group 1 20.1.1.4 20.1.1.10
[AR2]acl 2000
[AR2-acl-basic-2000]rule permit source 10.1.10.0 0.0.0.255
[AR2-GigabitEthernet0/0/1]nat outbound 2000 address-group 1
（3）配置NAT server，保证外部用户能够访问内网HTTP服务器
[AR1-GigabitEthernet0/0/1]nat server protocol tcp global 20.1.1.2 inside 10.1.7.30
[AR2-GigabitEthernet0/0/1]nat server protocol tcp global 20.1.2.3 inside 10.1.7.30
8.配置防火墙双机热备
（1）在防火墙上配置VGMP组监控上下行业务接口
[FW1]hrp track interface GigabitEthernet 1/0/0
[FW1]hrp track interface GigabitEthernet 1/0/4
[FW1]hrp track interface GigabitEthernet 1/0/2
[FW1]hrp track interface GigabitEthernet 1/0/1
[FW2]hrp track interface GigabitEthernet 1/0/0
[FW2]hrp track interface GigabitEthernet 1/0/3
[FW2]hrp track interface GigabitEthernet 1/0/1
[FW2]hrp track interface GigabitEthernet 1/0/2
（2）在防火墙配置根据HRP状态调整OSPF的相关COST值的功能
[FW1]hrp adjust ospf-cost enable
[FW2]hrp adjust ospf-cost enable
（3）在防火墙上指定心跳接口，启用双机热备
[FW1]hrp interface g1/0/6 remote 10.1.12.2
[FW1]hrp enable //启动HRP双机热备份功能
HRP_S[FW1]hrp mirror session enable //启动会话快速备份功能, 防火墙工作于双机热备份组网环境下，如果报文的来回路径不一致，通过配置会话快速备份功能，能够保证主用防火墙的会话信息立即同步至备用防火墙。当主用防火墙出现故障时，报文能够被备用防火墙转发出去，从而保证内外部用户的会话不中断
[FW2]hrp interface g1/0/6 remote 10.1.12.1
[FW2]hrp enable
HRP_S[FW2]hrp mirror session enable
（4）检查配置结果：本端和对端优先级相同，且状态都为active，说明两台防火墙处于负载分担状态
-
防火墙配置攻击防范：对于内部服务器，可能会遭受SYN Flood、HTTP Flood攻击，所以在防火墙上开启SYN Flood、HTTP Flood攻击防范功能，保护内部服务器不受攻击。
HRP_M[FW1]firewall defend udp-flood base-session max-rate 1500 (+B)
HRP_M[FW1]firewall defend icmp-unreachable enable (+B)
HRP_M[FW1]firewall blacklist enable (+B)
