预配置第一步：在R1上的预配置 R1(config)#int s1/2 R1(config-if)#ip add 10.1.1.1 255.255.255.0 R1(config-if)#no sh 第二步: 在R2上的预配置 R2(config)#int s2/1 R2(config-if)#ip add 10.1.1.2 255.255.255.0 R2(config-if)#no sh 实验过程：第一步：在R1上配置用户名与密码和PPP PAP认证 R1(config)#username R2 password cisco R1(config)#int s1/2 R1(config-if)#ppp authentication PAP R1(config-if)#ppp pap sent-username R1 password 0 cisco R1(config-if)#^Z R1# 第二步：在R2上配置用户名与密码和PPP PAP认证 R2(config)#username R1 password cisco R2(config)#int s2/1 R2(config-if)#ppp authentication pap R2(config-if)#ppp pap sent-username R2 password 0 cisco R2(config-if)#^Z R2# 第三步：在R1上调试PPP认证过程 R1#debug ppp authentication PPP authentication debugging is on R1#conf t Enter configuration commands, one per line. End with CNTL/Z. R1(config)#int s1/2 R1(config-if)#sh R1(config-if)# 00:06:11: %LINK-5-CHANGED: Interface Serial1/2, changed state to administratively down 00:06:12: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/2, changed state to down R1(config-if)#no sh R1(config-if)# 00:06:19: %LINK-3-UPDOWN: Interface Serial1/2, changed state to up R1(config-if)# 00:06:19: Se1/2 PPP: Treating connection as a dedicated line 00:06:19: Se1/2 PPP: Phase is AUTHENTICATING, by both 00:06:19: Se1/2 PAP: O AUTH-REQ id 3 len 13 from "R1" 00:06:19: Se1/2 PAP: I AUTH-REQ id 3 len 13 from "R2" 00:06:19: Se1/2 PAP: I AUTH-ACK id 3 len 5 00:06:19: Se1/2 PAP: Authenticating peer R2 00:06:19: Se1/2 PAP: O AUTH-ACK id 3 len 5 （通过认证） R1(config-if)# 第四步：在R1上查看路由表是否学习到了对方的接口 R1#sh ip rout Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate default U - per-user static route, o - ODR T - traffic engineered route
