[R5-LoopBack1]ip add 5.5.5.5 24
边界路由器到ISP通
将R1、R2、R3、R4当做内网的边界路由器，R5当做ISP运营商，所以边界路由器需要配置缺省路由指向自己公网的运营商设备
[R1]ip route-static 0.0.0.0 0 15.1.1.2
[R2]ip route-static 0.0.0.0 0 25.1.1.2
[R3]ip route-static 0.0.0.0 0 35.1.1.2
[R4]ip route-static 0.0.0.0 0 45.1.1.2

PAP认证
R5 主认证方
[R5]aaa
[R5-aaa]local-user xixi password cipher xixi123
Info: Add a new user.
[R5-aaa]local-user xixi service-type ppp
[R5-aaa]int s3/0/0 连接客户端的接口
[R5-Serial3/0/0]link-protocol ppp
[R5-Serial3/0/0]ppp authentication-mode pap
此时被认证方R1pingR5的接口不通
被认证方R1
[R1]int s4/0/0
[R1-Serial4/0/0]link-protocol ppp
[R1-Serial4/0/0]ppp pap local-user xixi password cipher xixi123
R1做完认证再次pingR5的接口
CHAP认证
R5主认证方
[R5]aaa
[R5-aaa]local-user heihei password cipher heihei123
Info: Add a new user.
[R5-aaa]local-user heihei service-type ppp
[R5-aaa]int s3/0/1
[R5-Serial3/0/1]link-protocol ppp
[R5-Serial3/0/1]ppp authentication-mode chap
被认证方
[R2]int s4/0/0
[R2-Serial4/0/0]link-protocol ppp
[R2-Serial4/0/0]ppp chap user heihei
[R2-Serial4/0/0]ppp chap password cipher heihei123
R2完成认证ping连接R5的接口
R3与R5间使用HDLC封装
[R3-Serial4/0/0]link-protocol hdlc
Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]

当拓扑结构为中心到站点（轴辐状、星型）——不是所有网点均为固定的公有IP、没法所有tunnel设备互相注册，只能通过关闭水平分割来实现路由的全网正常收敛；
