You are configuring a PPP connection between two routers, R1 and R2. The password for the connection will be poppycock. When you are finished you execute the show run command on R1 to verify the configuration. Which of the following examples of partial output of the show run command from R1 represents a correct configuration of PPP on R1?

A.	`enable password griswald ! hostname R1 ! username R1 password poppycock ! interface serial 0/0 ip address 192.168.5.5 255.255.255.0 encapsulation ppp ppp authentication chap !`
B.	`enable password griswald ! hostname R1 ! username R1 password poppycok ! interface serial 0/1 ip address 192.168.5.5 255.255.255.0 encapsulation ppp ppp authentication chap`
C.	`enable password griswald ! hostname R1 ! username R2 password poppycock ! interface serial 0/0 ip address 192.168.5.5 255.255.255.0 encapsulation ppp ppp authentication chap`
D.	`enable password griswald ! hostname R1 ! username R1 password griswald ! interface serial 0/0 ip address 192.168.5.5 255.255.255.0 encapsulation ppp ppp authentication chap`

Accepted Answer


enable password griswald 
!
hostname R1

username R2 password poppycock 
!
interface serial 0/0 
 ip address 192.168.5.5 255.255.255.0

Accepted Answer

The correct configuration is as follows:


enable password griswald 
!
hostname R1 
!
username R2 password poppycock 
!
interface serial 0/0 
 ip address 192.168.5.5 255.255.255.0 
 encapsulation ppp ppp 
 authentication chap

The key settings that are common problems are as follows:
* The username is set to the hostname of the other router (in this case, R2)
* The password is set poppycock which must be the same in both routers

The following set is incorrect because the username is set to the local hostname (R1) and not the hostname of the other router (R2):


enable password griswald 
!
hostname R1 
!
username R1 password poppycock 
!
interface serial 0/0 
 ip address 192.168.5.5 255.255.255.0 
 encapsulation ppp ppp 
 authentication chap 
!

The following set is incorrect because the password is misspelled. It should be poppycock, not poppycok.


enable password griswald 
!
hostname R1 
!
username R1 password poppycok 
!
interface serial 0/1
 ip address 192.168.5.5 255.255.255.0 
 encapsulation ppp ppp 
 authentication chap

The following set is incorrect because the password is set to the enable password of the local router (R1) rather than the agreed upon PPP password, which is
poppycock.


enable password griswald 
!
hostname R1 
!
username R1 password griswald 
!
interface serial 0/0
 ip address 192.168.5.5 255.255.255.0 
 encapsulation ppp ppp
