CISCO路由器CHAP認證配置
- 思科認證
- 關注:2.29W次
在配置PPP驗證時有PAP和CHAP的選擇,其中PAP為明文傳送用户名和口令,不安全。而CHAP則採用哈希值進行驗證,口令不會在網上傳送,所以安全性比較高。
CHAP認證也是CCNA課程PPP教學時所需掌握的基本配置,其配置如下:
拓撲: RA DTE--------DCE RB
--------------------------------------
RA#conf t
RA(config)#username RB password hello
RA(config)#int s0
RA(config-if)#encap ppp
RA(config-if)#ppp au chap
RA(config-if)#end
-------------------------------
Router(config)#host RB
RB(config)#username RA password hello
RB(config)#int s0
RB(config-if)#encap ppp
RB(config-if)#ppp auth chap
