​​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

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

​

Lilo

 

int lo 0
ip address 10.1.1.1 255.255.255.0

 

int s1/0
no shut
ip address 172.16.1.1 255.255.255.252

 

​

 

Stitch

 

  int lo 0
  ip address 10.1.2.1 255.255.255.0

​

  int s1/0
  ip address 172.16.1.2 255.255.255.252
  no shut

​

Lilo

 

  int s1/0
  bandwidth 64
 

​

 

Stitch

 

  int s1/0
  bandwidth 64

​

Lilo

 

  ip route 10.1.2.0 255.255.255.0 172.16.1.2

​

 

Stitch

 

 ip route 10.1.1.0 255.255.255.0 172.16.1.1

 

​

 

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

​

Lilo

​

  int s1/1
  encapsulation ppp

  bandwidth 64
 

  int s1/0
  no ip address
  exit
 

  interface multilink 1
  encapsulation ppp
  ppp multilink
  ip address 172.16.1.1 255.255.255.252

  ppp multilink group 1 !------------------------create a multilink group

​

  int s1/0
  ppp multilink group 1 !-----------------------add int s1/0 as part of group 1
  int s1/1
  ppp multilink group 1 !-----------------------add int s1/1 as part of group 1




Stitch

​

  int s1/1 

  encapsulation ppp

  bandwidth 64

​

  int s1/0
  no ip add
 

  interface multilink 1
  ip address 172.16.1.2 255.255.255.252
  encapsulation ppp

  ppp multilink
  ppp multilink group 1

 

  int s1/0
  ppp multilink group 1
  int s1/1
  ppp multilink group 1
