Exchange Comprehensive Experiment

实验要求如下

Analyze the experiment first,Complete the topology design
进行ip地址规划
172.16.0.0/24 骨干 172.16.0.0/30 172.16.0.4/30
172.16.1.0/24 vlan1 172.16.1.0/25 172.16.1.128/25
ip地址分配好后
创建eth-trunk绑定接口

[SW3]int Eth-Trunk 1
[SW3-Eth-Trunk1]q
[SW3]int g0/0/01
[SW3-GigabitEthernet0/0/1]eth-trunk 1
[SW3]int g0/0/2
[SW3-GigabitEthernet0/0/2]eth-trunk 1

然后创建vlan
在SW1/SW2连接PC处的接口化为vlan2

SW2]int e0/0/3
[SW2-Ethernet0/0/3]port link-type access
[SW2-Ethernet0/0/3]port default vlan 1
[SW2-Ethernet0/0/3]int e0/0/04
[SW2-Ethernet0/0/4]port link- access
[SW2-Ethernet0/0/4]port default vlan 2

划分trunk干道
SW3/SW4都可以按此方法划分trunk

[SW3]port-group group-member Eth-Trunk 1 GigabitEthernet 0/0/3 to g0/0/04
[SW3-port-group]port link-type trunk
[SW3-GigabitEthernet0/0/3]port trunk allow-pass vlan 2

SW1/SW2划入trunk

[SW1]port-group group-member Ethernet 0/0/1 to Ethernet 0/0/02
[SW1-port-group]port link-type trunk
[SW1-port-group]port trunk allow-pass vlan 2

配置STP生成树
因为华为设备中默认是MSTP;
SW1/SW2/SW3/SW4均按照此配置进行配置

[SW4]stp re
[SW4]stp region-configuration
[SW4-mst-region]region-name a
[SW4-mst-region]instance 1 vlan 1
[SW4-mst-region]instance 2 vlan 2
[SW4-mst-region]active region-configuration

将交换机连接电脑的接口调整为生成树的边缘接口,连接用户,这样可以响应速度更快,连电脑接口只需要一次bpdu收发就行
在SW1/SW2上进行配置

[SW2]port-group group-member Ethernet 0/0/03 to Ethernet 0/0/4
[SW2-port-group]stp edged-port enable
[SW2-Ethernet0/0/3]stp edged-port enable
[SW2-Ethernet0/0/4]stp edged-port enable

配置好SVI和VRRP后,开始配置dhcpaddress below

[SW3]dhcp enable
[SW3]ip pool 1
[SW3-ip-pool-1]network 172.16.1.0 mask 25
[SW3-ip-pool-1]gateway-list 172.16.1.126
[SW3-ip-pool-1]dns-list 8.8.8.8
[SW3]ip pool 2
[SW3-ip-pool-2]network 172.16.1.128 mask 25
[SW3-ip-pool-2]gateway-list 172.16.1.254
[SW3-ip-pool-2]dns-list 8.8.8.8
[SW3]int Vlanif 1
[SW3-Vlanif1]dhcp select global
[SW3-Vlanif1]int vl2
[SW3-Vlanif2]dhcp select global

查看pc的ip地址

然后开始配置ospf

[SW3]ospf 1 router-id 1.1.1.1
[SW3-ospf-1-area-0.0.0.0]network 172.16.0.0 0.0.255.255

[SW4]ospf 1 router-id 2.2.2.2
[SW4-ospf-1]area 0
[SW4-ospf-1-area-0.0.0.0]network 172.16.0.0 0.0.255.255

在R1上配置一条缺省路由,并在OSPF域内重发布

R1]ip route-static 0.0.0.0 0.0.0.0 12.1.1.2
[R1]ospf 1
[R1-ospf-1]default-route-advertise

配置NAT地址转换,使内网地址访问公网可以通过NAT转换

R1]acl 2000
[R1-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]nat outbound 2000

测试pc访问公网
