[Day 10] 12. Commands for encapsulating CHAP and PAP

Router A Configuration

1. Enter Interface Configuration:
   

   Copy

   A(config)# interface s0

2. Set PPP Encapsulation:
   

   Copy

   A(config-if)# encapsulation ppp

3. Configure PPP with CHAP and PAP:

   Copy

   A(config-if)# ppp encapsulation chap pap

4. Exit Interface Configuration:

   Copy

   A(config-if)# exit

5. Set Username for Router B:

   Copy

   A(config)# username B password cisco

Router B Configuration

1. Enter Global Configuration:

   Copy

   B(config)#

2. Set Username for Router A:

   Copy

   B(config)# username A password cisco

Key Points

• Matching Passwords: Ensure that the passwords for the usernames on both routers are identical. In this example, both routers A and B have their usernames configured with the password "cisco."

• Authentication Methods: While the configuration includes both CHAP and PAP, typically only one method is used at a time for authentication. Make sure you choose the desired method based on your security requirements.
