Cisco ppp Configuration

We know that PPP and point-to-point protocols are commonly used. Related settings are available on many devices. Here we will give a detailed explanation of the configuration of cisco ppp. Let's take a closer look at the authentication configuration involved.

Cisco ppp configuration 1: PAP authentication configuration for PPP

R1: (the primary authenticated party is also the authenticated party)

 
 

  
  
hostname r1  
  
  
username r2 password yhp  
  
  
int s0/0  
  
  
ip add 192.200.10.1 255.255.255.0  
  
  
encapsulation ppp  
  
  
ppp authentication pap  
  
  
ppp pap sent-username r1 password yhp  
  
  
no shutdown 
 
 

Optional

 
 

  
  
Peer default ip address 192.200.10.2 --------- negotiate IP address
  
  
Compress {predictor | stac}
  
  
Ip tcp header-compress
 
 

R2: (the primary authenticated party is also the authenticated party)

 
 

  
  
hostname r2  
  
  
username r1 password yhp  
  
  
int s0/0  
  
  
ip add 192.200.10.2 255.255.255.0  
  
  
encapsulation ppp  
  
  
ppp authentication pap  
  
  
ppp pap sent-username r2 password yhp  
  
  
no shutdown 
 
 

Optional

 
 

  
  
Ip address nego ------------------------------------- set with the same end
  
  
Compress {predictor | stac}
  
  
Ip tcp header-compress
 
 

Cisco ppp configuration 2: CHAP authentication configuration for PPP

Method 1

R1: (primary authenticated party)

 
 

  
  
hostname r1  
  
  
username r2 pass yhp  
  
  
int s0/0  
  
  
ip add 192.200.10.1 255.255.255.0  
  
  
encapsulation ppp  
  
  
ppp authentication chap  
  
  
no shutdown 
 
 

R2: (authenticated party)

 
 

  
  
hostname r2  
  
  
username r1 pass yhp  
  
  
int s0/0  
  
  
ip add 192.200.10.2 255.255.255.0  
  
  
encapsulation ppp  
  
  
ppp authentication chap  
  
  
no shutdown 
 
 

Method 2

R1: (primary authenticated party)

 
 

  
  
hostname r1  
  
  
username r2 pass cisco  
  
  
int s0/0  
  
  
ip add 192.200.10.1 255.255.255.0  
  
  
encapsulation ppp  
  
  
ppp authentication chap  
  
  
no shutdown 
 
 

R2: (authenticated party)

 
 

  
  
hostname r2  
  
  
username r1 pass cisco  
  
  
int s0/0  
  
  
ip add 192.200.10.2 255.255.255.0  
  
  
encapsulation ppp  
  
  
ppp authentication chap  
  
  
ppp chap hostname yhp  
  
  
no shutdown 
 
 

Note: If the PPP compression method is required, the [ppp pap configuration], DCE, and DTE must be configured separately.
