VTP 同步 捆绑 并且负载均衡 在DHCP地址池获取ip地址
在R1上配置
R1>en
R1#conf t
R1(config)#vlan 10
添加vlan
R1(config-vlan)#vlan 20
R1(config)#interface range f1/0 -1

添加地址池
R1(dhcp-config)#network 192.168.10.0 255.255.255.0
地址
R1(dhcp-config)#default-router 192.168.10.1
默认网关
R1(dhcp-config)#ip dhcp pool v20

R1(dhcp-config)#network 192.168.20.0 255.255.255.0
在R2上配置
R2>en

R2(config-if)#switchport access vlan 10
R2(config)#no ip routing
路由功能关了
R2(config)#vtp domain hao.com

Changing VTP domain name from NULL to hao.com
R2(config)#vtp mode server
把vtp模式改成服务器
Setting device to VTP SERVER mode
R2(config)#vtp version 2
版本为2
Cannot modify version in VTP client mode
R2(config)#vtp password 123

R2(config-if-range)#inter f1/2
做成中继口
R2(config-if)#switchport mode trunk

R2#conf t
R2(config)#inter f1/5
R2(config-if)#shut
R2(config-if)#no shut
重新关闭然后再开启！
R2(config-if)#

R3#conf t
R3(config)#inter f1/0
划分端口进vlan
R3(config-if)#switchport access vlan 20
R3(config-if)#inter f1/2
设置成中继口
R3(config-if)#switchport mode trunk
R3(config-if)#switchport trunk encapsulation dot1q
R3(config)#no ip routing
R3(config)#interface range fastEthernet 1/3 -5

R3(config-if-range)#channel-group 1 mode on
Creating a port-channel interface Port-channel1
R3(config-if-range)#
R3(config-if-range)#
R3(config-if-range)#end
测试结果，dhcp获取地址，并且能ping通别的vlan成员
