当前H3C最新版模拟器加入了防火墙、AC、AP、Phone等新设备,本文重点介绍新设备的使用
整体规划
采用三层网络结构,核心、汇聚、防火墙、AC、DHCP服务器均采用三层链接,AP采用三层上线,管理业务分离
功能实现
1、ospf三层互联,为简化网络,不配置lookback接口
2、配置DHCP服务器,配置DHCP中继,为多个VLAN提供服务
3、外网通过防火墙NAT访问
最终目标
实现Phone通过AP联网并自动获取IP,能够访问外网1.1.1.1
配置步骤
1、配置核心交换机
配置三层接口
interface GigabitEthernet1/0/1
port link-mode route
combo enable fiber
ip address 10.0.0.2 255.255.255.252
#
interface GigabitEthernet1/0/2
port link-mode route
combo enable fiber
ip address 10.0.0.9 255.255.255.252
#
interface GigabitEthernet1/0/3
port link-mode route
combo enable fiber
ip address 10.0.0.6 255.255.255.252
#
interface GigabitEthernet1/0/4
port link-mode route
combo enable fiber
ip address 10.0.0.13 255.255.255.252
配置ospf协议
ospf 1
area 0.0.0.0
network 10.0.0.0 0.0.0.3
network 10.0.0.4 0.0.0.3
network 10.0.0.8 0.0.0.3
network 10.0.0.12 0.0.0.3
2、配置DHCP服务器
使用路由器模拟,配置接口
interface GigabitEthernet1/0/2
port link-mode route
combo enable fiber
ip address 10.0.0.10 255.255.255.252
配置ospf
ospf 1
area 0.0.0.0
network 10.0.0.8 0.0.0.3
配置dhcp池
dhcp enable
dhcp server ip-pool vlan10
gateway-list 10.0.1.254
network 10.0.1.0 mask 255.255.255.0
dns-list 10.0.0.1
#
dhcp server ip-pool vlan20
gateway-list 10.0.2.254
network 10.0.2.0 mask 255.255.255.0
dns-list 10.0.0.1
#
dhcp server ip-pool vlan30
gateway-list 10.0.3.254
network 10.0.3.0 mask 255.255.255.0
dns-list 10.0.0.1
3、配置汇聚交换机
配置VLANIF与三层接口
interface Vlan-interface10
ip address 10.0.1.254 255.255.255.0
dhcp select relay
dhcp relay server-address 10.0.0.10
#
interface Vlan-interface20
ip address 10.0.2.254 255.255.255.0
dhcp select relay
dhcp relay server-address 10.0.0.10
#
interface Vlan-interface30
ip address 10.0.3.254 255.255.255.0
dhcp select relay
dhcp relay server-address 10.0.0.10
#
interface GigabitEthernet1/0/4
port link-mode route
combo enable fiber
ip address 10.0.0.14 255.255.255.252
配置OSPF
ospf 1
area 0.0.0.0
network 10.0.0.12 0.0.0.3
network 10.0.1.0 0.0.0.255
network 10.0.2.0 0.0.0.255
network 10.0.3.0 0.0.0.255
开启DHCP中继服务
dhcp enable
4、调试pc
配置汇聚交换机对应接口为vlan10
interface GigabitEthernet1/0/6
port link-mode bridge
port access vlan 10
combo enable fiber
PC配置自动获取,成功获取IP
5、防火墙
将 本地主机 vbox网卡接口 与 防火墙相连,登陆防火墙,为接口配置IP地址。
我的vbox网卡地址为192.168.56.254
为防火墙配置192.168.56.2
interface GigabitEthernet1/0/0
port link-mode route
combo enable copper
ip address 192.168.56.2 255.255.255.0
配置acl规则,允许此接口进行web登录
acl advanced 3000
rule 0 permit ip
为接口引入规则
security-zone name Management
import interface GigabitEthernet1/0/0
#
zone-pair security source Local destination Management
packet-filter 3000
#
zone-pair security source Management destination Local
packet-filter 3000
登录防火墙进行配置adminadmin
配置内网接口
配置外网接口
配置防火墙静态路由,从防火墙返回内网的路由
配置防火墙安全策略,所有区域互通
配置NAT转换
配置核心默认路由,声明ospf默认路由
ip route-static 0.0.0.0 0 10.0.0.1
ospf 1
default-route-advertise
配置外网设备1.1.1.1,配置IP
interface GigabitEthernet0/2
port link-mode route
combo enable copper
ip address 1.1.1.1 255.255.255.0
测试pc与防火墙内外网地址互通,实现通讯
ping 1.1.1.2
Ping 1.1.1.2 (1.1.1.2): 56 data bytes, press CTRL_C to break
56 bytes from 1.1.1.2: icmp_seq=0 ttl=253 time=1.000 ms
注意,多外网接口通讯还需配置策略路由
防火墙配置至此完成
6、AC配置
断开本地主机与防火墙的连接,将本地主机连接至AC
为ac配置IP并配置web登录
[ac]int vlan 1
[ac-Vlan-interface1]ip add 192.168.56.3 24
[ac]ip http en
[ac]local-user admin
New local user added.
[ac-luser-manage-admin]password simple pass@123456
[ac-luser-manage-admin]authorization-attribute user-role level-15
[ac-luser-manage-admin]service-type http
[ac-luser-manage-admin]save
因模拟器存在bug,将AC接口改为三层接口后所有接口失效,因此为AC和核心交换机配置trunk及vlan,若已经触发bug,需要删除AC重新添加
核心配置
interface Vlan-interface100
ip address 10.0.0.6 255.255.255.252
interface GigabitEthernet1/0/3
port link-mode bridge
port link-type trunk
port trunk permit vlan all
combo enable fiber
AC配置
interface Vlan-interface100
ip address 10.0.0.5 255.255.255.252
interface GigabitEthernet1/0/3
port link-mode bridge
port link-type trunk
port trunk permit vlan all
为AC设置默认路由
ip route-static 0.0.0.0 0 10.0.0.6
使用pc测试,可以与AC通讯
ping 10.0.0.5
Ping 10.0.0.5 (10.0.0.5): 56 data bytes, press CTRL_C to break
56 bytes from 10.0.0.5: icmp_seq=0 ttl=253 time=2.000 ms
为DHCP服务器配置option43选项,AP上线网段为VLAN20
option43格式简要说明:
80 07 00 00 01 02 02 02 02
80:固定值,不用改变;
07:长度字段,其后面所跟数据的字节长度;
00 00:固定值,不用改变;
01:表示后面的IP地址的个数,此处为一个IP地址;
02 02 02 02:IP地址
在线转换工具https://tool.520101.com/wangluo/jinzhizhuanhuan/
10.0.0.5 = A000005
拼接默认字段option 43 hex 80070000010A000005,位数不够补零
DHCP服务器配置
dhcp server ip-pool vlan20
gateway-list 10.0.2.254
network 10.0.2.0 mask 255.255.255.0
dns-list 10.0.0.1
option 43 hex 80070000010a000005
汇聚为AP对应的接口配置trunk及默认pvid
interface GigabitEthernet1/0/5
port link-mode bridge
port link-type trunk
port trunk permit vlan all
port trunk pvid vlan 20
重启AP,查看获取IP情况
查看IP
dis int br
Vlan1 UP UP 10.0.2.1
登录ac,开启自动AP
进行AP固化及重命名
创建本地转发网络
为ap创建map文件,vlan30为业务vlan
自定义名字officecfg.txt,因为接口配置了pvid,所以对ap来说,管理vlan是vlan1,不需要再配置
system-view
vlan 30
quit
interface GigabitEthernet 0/0/0
port link-type trunk
port trunk permit vlan 30
在AP上部署map文件
在AP上部署无线网络,vlan填写业务vlan 30
客户端联网测试,成功获取vlan30的ip
phone ping通外网1.1.1.1,实验完成
小结
华三模拟器,牛逼!
