1、广域网技术
HDLC封装、思科私有
PPP封装，在PPP上可以做PAP和CHAP认证，PAP是明文认证，CHAP是加密认证
2、路由
2.1 静态路由
R2:
enable
configure terminal
no ip domain-lookup
line console 0
logging synchronous
interface FastEthernet0/0
no shutdown
ip address 192.168.23.2 255.255.255.0
interface FastEthernet0/1
no shutdown
ip address 192.168.12.2 255.255.255.0
exit
ip route 192.168.1.0 255.255.255.0 192.168.12.1
ip route 192.168.4.0 255.255.255.0 192.168.23.3
end

2.2 RIP

enable
configure terminal
no ip domain-lookup
