若何在三层交换机上实现跨VLAN 的DHCP设置装备摆设
3550交换机上的设置装备摆设:
vlan database(划分VLAN)
vlan 2
vlan 3
interface FastEthernet0/2(将端口f0/2划分进vlan2)
switchport access vlan 2
switchport mode access
no ip address
interface FastEthernet0/3(将端口f0/3划分进vlan3)
switchport access vlan 3
switchport mode access
no ip address
interface Vlan1
ip address 192.168.1.2 255.255.255.0
ip helper-address 192.168.1.1 (将DHCP恳求的播送数据包转化为单播恳求,路由器才会响应)
interface Vlan2
ip address 192.168.2.1 255.255.255.0
ip helper-address 192.168.1.1
interface Vlan3
ip address 192.168.3.1 255.255.255.0
ip helper-address 192.168.1.1
路由器2621上的设置装备摆设:
ip dhcp pool tyl-01(设置装备摆设第一个VLAN的地址池)
network 192.168.1.0 255.255.255.0
default-router 192.168.1.1 (设置装备摆设PC网关)
dns-server 202.96.134.133(设置装备摆设DNS办事器)
ip dhcp pool tyl-02(设置装备摆设第二个VLAN的地址池)
network 192.168.2.0 255.255.255.0
default-router 192.168.2.1
dns-server 202.96.134.133
ip dhcp pool tyl-03(设置装备摆设第三个VLAN的地址池)
network 192.168.3.0 255.255.255.0
default-router 192.168.3.1
dns-server 202.96.134.133
ip route 192.168.2.0 255.255.255.0 192.168.1.2(设置装备摆设静态路由)
ip route 192.168.3.0 255.255.255.0 192.168.1.2
ip dhcp excluded-address 192.168.1.1 192.168.1.2 (将路由器F0/0和3550 VLAN1的IP 地址肃清)
ip dhcp excluded-address 192.168.2.1 (3550 VLAN1的IP 地址肃清)
ip dhcp excluded-address 192.168.3.1 (3550 VLAN1的IP 地址肃清)
