2.广域网链路配置要求：
R1与R2之间封装PPP，采用PAP方式认证；R2与R3之间封装PPP，采用CHAP认证。
- 路由器基本配置

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
R1(config-if)#int lo 0
R1(config-if)#
%LINK-5-CHANGED: Interface Loopback0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback0, changed state to up
R1(config-if)#ip add 192.168.1.10 255.255.255.248
- R1与R2之间封装PPP，采用PAP方式认证

%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0, changed state to up
R2(config-if)#
R2(config-if)#do ping 192.168.1.113
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.113, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/9 ms
R2(config-if)#

3.R1直连的PC动态的获取IP地址-DHCP
R1(config)#ip dhcp pool R1_DHCP
R1(dhcp-config)#network 192.168.1.32 255.255.255.224
R1(dhcp-config)#default
R1(dhcp-config)#default-router 192.168.1.33
R1(dhcp-config)#exi
R1(config)#ip dhcp ex
R1(config)#ip dhcp excluded-address 192.168.1.33 192.168.1.43
R1(config)#
查看PC1获取地址情况
PC>ipconfig
FastEthernet0 Connection:(default port)
Link-local IPv6 Address.........: FE80::206:2AFF:FE6A:7E03
IP Address......................: 192.168.1.44
Subnet Mask.....................: 255.255.255.224
Default Gateway.................: 192.168.1.33
4.三层路由功能
全网运行OSPF路由协议，要求如下：
使用精确的通配符掩码将必要的接口加入OSPF进程，本地进程号为X；
所有接口包括环回接口都属于骨干区域，禁止额外的区域；
路由器ID使用环回接口的地址；
