简单中继实验

实验目的

将AR1作为DHCP服务器为pc机分配地址，AR2为中继器（中继器的作用是放大信号，补偿信号衰减，支持远距离的通信）

实验配置思路

先将路由器配置打通，在再AR1上配置DHCP,AR2上配置中继

AR1配置

 sysname AR1
#
vlan batch 10
#
dhcp enable
#
ip pool 1
 gateway-list 192.168.2.1 
 network 192.168.2.0 mask 255.255.255.0 
 lease day 3 hour 0 minute 0 
 dns-list 192.168.2.1 
#
interface Vlanif10
 ip address 192.168.1.1 255.255.255.0 
 dhcp select global
#
interface Ethernet0/0/0
 port link-type trunk
 port trunk allow-pass vlan 10
#
ip route-static 0.0.0.0 0.0.0.0 192.168.1.2

 AR2

 sysname AR2
#
vlan batch 10 20
#
interface Vlanif10
 ip address 192.168.1.2 255.255.255.0 
#
interface Vlanif20
 ip address 192.168.2.1 255.255.255.0 
 dhcp select relay
 dhcp relay server-ip 192.168.1.1
#
interface Ethernet0/0/1
 port link-type access
 port default vlan 20
