1. Configurer PAP
Creer sur:
R1 HOMER password duffman
R0 LENNY password carlita
2. Configurer CHAP
R1, R2: password nucleaire
3. Protocol de routage: OSPF
****************************************************
Correction
****************************************************1.- Configuration des interfaces:
`````````````````````````````
R0:
int f0/0
ip address 10.0.0.126 255.255.255.128
no shutdown
exit
int s0/1/0
ip address 1.1.1.1 255.255.255.252
clock rate 56000
bandwidth 56
no shut
R1:
int f0/0
ip address 10.0.1.62 255.255.255.192
no shutdown
exit
int s0/1/1
ip address 1.1.1.2 255.255.255.252
no shutdown
bandwidth 56
int s0/1/0
ip address 1.1.1.5 255.255.255.252
clock rate 56000
bandwidth 56
no shutdown
R2:
int s0/1/1
ip address 1.1.1.6 255.255.255.252
no shutdown
bandwidth 56
int f0/0
ip address 10.0.2.30 255.255.255.224
no shutdown
2.- Configuration des DHCP:
`````````````````````````````
R0:
ip dhcp pool LAN0
network 10.0.0.0 255.255.255.128
default-router 10.0.0.126
dns-server 8.8.8.8
exit
ip dhcp excluded-address 10.0.0.126
R1:
ip dhcp pool LAN1
network 10.0.1.0 255.255.255.192
default-router 10.0.1.62
dns-server 8.8.8.8
exit
ip dhcp excluded-address 10.0.1.1 10.0.1.10
R2:
ip dhcp pool LAN2
network 10.0.2.0 255.255.255.224
default-router 10.0.2.30
dns-server 8.8.8.8
exit
ip dhcp excluded-address 10.0.2.30
3.- Mise en place de PPP et PAP entre R0 et R1:
````````````````````````````````````````````````
R0:
int S0/1/0
encapsulation ppp
ppp authentication pap
ppp pap sent-username HOMER password duffman
R1:
int S0/1/1
encapsulation ppp
ppp authentication pap
ppp pap sent-username LENNY password carlita
4.- Creation des usernames sur R0 et R1:
`````````````````````````````````````````
R0:
username LENNY password carlita
R1:
username HOMER password duffman
5.- Configuration de PPP CHAP entre R1 et R2:
`````````````````````````````````````````
R1:
int s0/1/0
encapsulation ppp
ppp authentication chap
exit
hostname R1
enable password nucleaire
NB: dans packet tracer, nous sommes obligé d'utiliser le "hostname" et le "enable password" pour l'authentification CHAP.
R2:
int s0/1/1
encapsulation ppp
ppp authentication chap
exit
hostname R2
enable password nucleaire
6.- Creation des usernames pour l'auth CHAP:
```````````````````````````````````````````````
R1:
username R2 password nucleaire
R2:
username R1 password nucleaire
7.- Pour vérifier PPP:
``````````````````````
#show interface serial
-> affiche l'état du lien (LCP Open/Close)
l'encapsulation, et les protocoles négociés via NCP
# debug ppp negociation
-> affiche en temps reel sur la ligne console la négociation du lien (échanges LCP)
# debug ppp authentication
-> affiche l'auth en temps reel sur la ligne console
R1#show int s0/1/0
Serial0/1/0 is up, line protocol is up (connected)
Hardware is HD64570
Internet address is 1.1.1.5/30
MTU 1500 bytes, BW 128 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation PPP, loopback not set, keepalive set (10 sec)
LCP Open
Open: IPCP, CDPCP <== protocol negocie via NCP
LCP Link Control Protocol
NCP Network Control Protocol
8.- Configuration d'OSPF:
```````````````````````````
R0:
router ospf 51
network 10.0.0.0 0.0.0.127 area 0
networ 1.1.1.0 0.0.0.3 area 0
passive-interface f0/0
R1:
router ospf 60
network 10.0.1.0 0.0.0.63 area 0
network 1.1.1.0 0.0.0.3 area 0
network 1.1.1.4 0.0.0.3 area 0
passive-interface f0/0
R2:
router ospf 74
network 10.0.2.0 0.0.0.31 area 0
networ 1.1.1.4 0.0.0.3 area 0
passive-interface f0/0
