Cisco: Frame Relay, Point-to-Multipoint

Le but ici est de partager les informations de routage OSPF via Frame-Relay.

Fichier a telecharger: FR_multipoint_clean.pkt
Logiciel: packet tracer

Configurer:

1. Les interfaces LANs
2. DHCP
3. Frame-Relay
4. OSPF

Notes:

PVC (Permanent Virtual Circuit)
DLCI (Data Link Connection Identifier)
LMI (Local Management Interface)

1.- Configuration des interfaces LAN:
`````````````````````````````````

R10X:
    int f0/0
     ip address 192.168.10.254 255.255.255.0
     description vers LAN10
     no shut

R20X:
    int f0/0
     ip address 192.168.20.126 255.255.255.128
     description vers LAN20
     no shut

R30X:
    int f0/0
     ip address 192.168.30.14 255.255.255.240
     description vers LAN30
     no shut


2.- Configuration des DHCP:
``````````````````````````````
L'option pour mettre une duree de bail n'est pas disponible dans Packet Tracer, sinon la commande serait:
Router(dhcp-config)#lease {days [hours][minutes]|infinite}
      (dhcp-config)#lease 0 12 <= duree du bail a 12h

R10X:
    ip dhcp pool LAN10
     network 192.168.10.0 255.255.255.0
     default-router 192.168.10.254
     dns-server 8.8.8.8 8.8.4.4

R20X:
    ip dhcp pool LAN20
     network 192.168.20.0 /25
     default-router 192.168.20.126
     dns-server 8.8.8.8 8.8.4.4

R30X:
    ip dhcp pool LAN30
     network 192.168.30.0 /28
     default-router 192.168.30.14
     dns-server 8.8.8.8 8.8.4.4


3.- Configuration de Frame-Relay:
```````````````````````````````````
-> Activation de FR ietf avec LMI de type ANSI:

R10X:
    int s2/0
     encapsulation frame-relay ietf
     frame-relay lmi-type ansi
     no shut
   
R20X:
    int s2/0
     encapsulation frame-relay ietf
     frame-relay lmi-type ansi
     no shut

R30X:
    int s2/0
     encapsulation frame-relay ietf
     frame-relay lmi-type ansi
     no shut
    

-> Creation du PVC entre R10X et R20X:

R10X:
