常用DHCP配置梳理

DHCP配置梳理

（1）dhcp select global  全局配置地址池

       DHCP的IP POOL配置在全局模式下，在接口上启用dhcp select global，接口应用全局的dhcp地址池。如建设一个有4个不同VLAN的域采用DHCP配置可以这样配。

    ip pool vlan2
 gateway-list 192.168.2.1
 network 192.168.2.0 mask 255.255.255.0
 excluded-ip-address 192.168.2.253 192.168.2.254
#
ip pool vlan3
 gateway-list 192.168.3.1
 network 192.168.3.0 mask 255.255.255.0
 excluded-ip-address 192.168.3.253 192.168.3.254
#
ip pool vlan4
 gateway-list 192.168.4.1
 network 192.168.4.0 mask 255.255.255.0
 excluded-ip-address 192.168.4.253 192.168.4.254
#
ip pool vlan5
 gateway-list 192.168.5.1
 network 192.168.5.0 mask 255.255.255.0
 excluded-ip-address 192.168.5.253 192.168.5.254

在int vlanif端口下启用dhcp select global

interface Vlanif2
 ip address 192.168.2.254 255.255.255.0
 vrrp vrid 2 virtual-ip 192.168.2.
