OSPF

OSPF (Open Shortest Path First) est un protocole de routage dynamiqueP de type "à état de liens".

 Règle :

Router(config)#router ospf process-id
Router(config-router)#network @ip-reseau-direct-connecté masque-générique area area-id
Router(config-router)#exit
masque-générique=(255.255.255.255 - masqueSousRéseau)

 Exemple : 

 

 sur Spade
Spade>enable 
Spade#configure terminal 
Spade(config)#interface fastEthernet 0/0
Spade(config-if)#no shutdown
Spade(config-if)#ip address 172.16.1.1 255.255.255.0
Spade(config-if)#exit
Spade(config)#interface fastEthernet 1/0
Spade(config-if)#ip address 192.168.12.1 255.255.255.0
Spade(config-if)#no shutdown
Spade(config)#router ospf 1
Spade(config-router)#network 192.168.12.0 0.0.0.255 area 0
Spade(config-router)#network 172.16.1.0 0.0.0.255 area 0
Spade(config-router)#exit

sur Hearts
