CCNA Skills Integration Challenge PT Activity 8.6.1 - Task 2

Task 2: Configure PPP with CHAP and PAP Authentication
Step 1. Configure the WAN link from HQ to ISP using PPP encapsulation and CHAP authentication.
The CHAP password is ciscochap.
We open console on HQ again and begin...

HQ>enable 
HQ#conf t
Enter configuration commands, one per line. End with CNTL/Z.
HQ(config)#interface serial 0/1/0
HQ(config-if)#ip address 209.165.201.1 255.255.255.252
HQ(config-if)#no shutdown 
%LINK-5-CHANGED: Interface Serial0/1/0, changed state to up
HQ(config-if)#encapsulation ppp 
HQ(config-if)#ppp authentication chap 
HQ(config-if)#exit
HQ(config)#username ISP password ciscochap 
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/1/0, changed state to up
do ping 209.165.201.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 209.165.201.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 6/8/14 ms
HQ(config)#do copy r s
Destination filename [startup-config]? 
Building configuration...
[OK]


Step 2. Configure the WAN link from HQ to NewB using PPP encapsulation and PAP authentication.You need to connect a cable to the correct interfaces. HQ is the DCE side of the link. You choose the clock rate. The PAP password is ciscopap.First of all we have to choose the cable for connecting. This job is easy enough. In the bottom of the PT we choose cable with clock label. First we connect it to DCE side of the link (HQ Serial 0/0/1), and the second connection will be serial 0/0/0 on NewB router. And now start to configure PPP using PAP authentification on HQ.
HQ(config)#interface serial 0/0/1
HQ(config-if)#ip address 10.255.255.253 255.255.255.252
HQ(config-if)#no shutdown 
%LINK-5-CHANGED: Interface Serial0/0/1, changed state to up
HQ(config-if)#encapsulation ppp
HQ(config-if)#ppp authentication pap 
HQ(config-if)#ppp pap sent-username HQ password ciscopap 
HQ(config-if)#exit
HQ(config)#username NewB password ciscopap
HQ(config)#interface serial 0/0/1
HQ(config-if)#clock rate 64000
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0/1, changed state to up
HQ(config-if)#do copy r s
Destination filename [startup-config]? 
Building configuration...
[OK]
HQ(config-if)#
And last thing that we need to do is adding new username and password on NewB for successful connection between routers.
NewB#conf t
Enter configuration commands, one per line. End with CNTL/Z.
NewB(config)#username HQ password ciscopap
NewB(config)#do copy r s
Destination filename [startup-config]? 
Building configuration...
[OK]

After veryfing pinging between HQ and ISP, HQ and NewB, you may start Task 3. On your Acrivity progress you will see 8% Completion.
