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
wr

2.2 RIP

R1:
enable
configure terminal
no ip domain-lookup
line console 0
logging synchronous

interface fastEthernet 0/0
no shutdown
ip addr 192.168.12.1 255.255.255.0

interface fastEthernet 0/1
no shutdown
ip addr 192.168.1.254 255.255.255.0

router rip
version 2
no auto-summary
network 192.168.1.0
network 192.168.12.0
end
