用电脑做单臂路由器要什么条件,同时要怎么设置
第一台电脑做DHCP服务器 用ROS或软路由软件控制/绑定第一块网卡
第二台电脑只做接受数据 不用设置 IP自动就可以
-------
VLAN是具有网管型二层交换机才有功能 路由器一般最多只有管理组的选用 这还是高级点的路由才有的功能 家用路由是没有管理组这个功能的
-----
单臂路由是网管型路由器 才有的功能 全部要由路由器的CONSOLE口对路由进行命令配置才能完成 也是要与二层交换机配套全用
cisco如何配置DHCP
1、随意选择路由器、交换机和多台主机。
2、用直线连接。
3、双击路由器,选择physical→cli,您将看到以下要配置的界面。
4、打开电脑,选择“桌面”—“IP配置”,然后选择DHCP。
5、最后,使用ping测试它,完成了。
在思科模拟器的路由器上怎么配置DHCP服务器?
1. 打开思科模拟器软件,找出一台2811类的路由器和两台2960类的交换机,4台PC电脑,并用正确的线缆将各个设备互相连接起来,如下图所示:
2.给所有设备都重新命名,路由器命名为r1,一交换机命名为sw1,另一交换机命名为sw2,如下图所示:
3. 先配置路由器r1先,配置命令为:
r1(config)#int f0/0
r1(config-if)#no sh
再配置路由器设备的远程登录和密码保护,配置命令为:
r1(config)#lin vty 0 4
r1(config-line)#login local
r1(config-line)#username admin password cisco
r1(config-line)#exit
r1(config)#enable secret cisco
r1(config)#service password-encrption (此命令为加密所有口令)
如下图所示:
4.配置交换机sw1,配置命令是:
sw1(config)#int vlan 1
sw1(config-if)#ip add 192.168.1.2 255.255.255.0
sw1(config-if)#no sh
sw1(config-if)#ex
sw1(config)#ip default-gateway 192.168.1.1
再用相同方法配置sw2,如下图所示:
5. 配置vlan设定,在sw1上划分vlan 2,3,将相应端口加入其中,配置命令为:
sw1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
sw1(config)#vlan 2
sw1(config-vlan)#ex
sw1(config)#vlan 3
sw1(config-vlan)#ex
sw1(config)#int f0/4
sw1(config-if)#switchport mode access
sw1(config-if)#switchport access vlan 2
sw1(config-if)#int f0/5
sw1(config-if)#switchport mode access
sw1(config-if)#switchport access vlan 3
sw1(config-if)#ex
用相同方法在sw3上面划分vlan,并将相应的端口加入其中,如下图所示:
6.配置单臂路由,实现valn1,2,3之间的互访,配置sw1接口f0/1为主干链路,配置命令是:
sw1(config)#int f0/1
sw1(config-if)#switchport mode trunk
sw1(config-if)#no sh
如下图所示:
7.在路由器r1上进行封装,配置命令如下图所示:
r1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
r1(config)#int f0/0
r1(config-if)#no shut
r1(config)#int f0/0.1
r1(config-subif)#encapsulation dot1Q 1
r1(config-subif)#ip add 192.168.1.1 255.255.255.0
r1(config-subif)#ex
r1(config)#int f0/0.2
r1(config-subif)#encapsulation dot1Q 2
r1(config-subif)#ip add 192.168.2.1 255.255.255.0
r1(config-subif)#ex
r1(config)#int f0/0.3
r1(config-subif)#encapsulation dot1Q 3
r1(config-subif)#ip add 192.168.3.1 255.255.255.0
r1(config-subif)#no sh
r1(config-subif)#ex
如下图所示:
8.配置DHCP服务器,即是配置路由器r1,配置命令是:
r1#enable
r1#conf t
r1(config)#ip dhcp excluded-address 192.168.2.1
r1(config)#ip dhcp pool vlan2
r1(dhcp-config)#net 192.168.2.0 255.255.255.0
r1(dhcp-config)#default-router 192.168.2.1
r1(dhcp-config)#dns-server 100.1.1.2
r1(config)#ip dhcp excluded-address 192.168.3.1
r1(config)#ip dhcp pool vlan3
r1(dhcp-config)#net 192.168.3.0 255.255.255.0
r1(dhcp-config)#dns-server 100.1.1.2
r1(dhcp-config)#ex
9. 现在PC之间可以自动获取IP地址和网关了,如下图所示:
三层交换机的DHCP配置
没用过思科的设备,命令都是大同小异,自己找下命令就行,首先先要把 dhcp 的 service 激活
,然后给你的interface 配置两个IP (主从)
ip address 11.1.1.1/24
ip address 11.1.2.1/24 secondary
然后就是配置DHCP SERVER上的 POOL 大致是这样 , 命令你自己在你设备上找,这是大概意思,
ip dhcp pool p1
network 11.1.1.0/24
default-router 11.1.1.1
range 11.1.1.2 11.1.1.200
dns-server 172.16.1.10
domain-name RG.COM
ip dhcp pool p2
network 11.1.2.0/24
default-router 11.1.2.1
range 11.1.2.2 11.1.2.150
dns-server 172.16.1.10
domain-name RG.com
下面的设备划了VLAN 给了IP 就可以了 不多说了 应该够了 ,,呵呵 要五星应该不过分,
