Looking at this web site , in PPP authentication commands:
http://www.howtonetwork.net/public/department98.cfm

When configured PPP with PAP or CHAP authentication, I have noticed the configuration is not the same on both routers that are authenticating each other:



Example for PAP Authentication:
R1(config)#int s1/1
 R1(config-if)#encapsulation ppp 
 R1(config-if)#ppp authentication pap
 R1(config-if)#exit
 R1(config)#username R3 password cisco
R3(config)#int s1/1
R3(config-if)#ppp pap sent-username R3 password cisco


Example for CHAP Authentication:

R1(config)#int s1/1
 R1(config-if)#encapsulation ppp 
 R1(config-if)#ppp authentication chap
 R1(config-if)#exit
 R1(config)#username R3 password cisco

R3(config-if)#int s1/1 
 R3(config-if)#encapsulation ppp
 R3(config-if)#ppp chap hostname R3
 R3(config-if)#ppp chap password cisco

I wonder if PPP authentication works in Client/Server way ? in the case authentication is set up in Server/Server way, how do we configure that ?
