Summary:
1. Configure the network in its entirely using HDLC encapsulation for the 64Kbps WAN link. Use static routing to provision full Lilo-to-Stitch office connectivity
2. Convert the link to PPP encapsulation
3. Configure PPP PAP authentication between Lilo and Stitch. Use the appropriate debug commands to prove authentication is occuring
4. Convert to using PPP CHAP authentication
5. Add a second WAN link between Lilo and Stitch, also running at 64Kbps. Engage PPP Multilink to double the bandwidth between the two locations

2. Convert the link to PPP encapsulation
Lilo
int s1/0
encapsulation ppp
Stitch
int s1/0
encapsulation ppp
3. Configure PPP PAP authentication between Lilo and Stitch. Use the appropriate debug commands to prove authentication is occurring
3.1 Create account
3.2 Assign credentials
3.3 Enable PAP
Lilo
username Stitch secret ninja
int s1/0
ppp pap sent-username Lilo password abc123
ppp authentication pap
! debug ppp authentication
! debug ppp negotiation
! show debug
! u all
Stitch
username Lilo secret abc123
int s1/0
ppp pap sent-username Stitch password ninja
ppp authentication pap
4. Convert to using PPP CHAP authentication (pwd has to be the same from both sites)
Lilo
username Stitch password 12345
int s1/0
ppp authentication chap
Stitch
username Lilo password 12345
int s1/0
ppp authentication chap
5. Add a second WAN link between Lilo and Stitch, also running at 64Kbps. Engage PPP Multilink to double the bandwidth between the two locations
- note another way to implement LB is via Equal cost static routes
