Bonjour,
J'ai un probleme pour la mise ne place de routage inter vlan
j'ai deux switch 2950 relier avec routeur cisco 1721
ma config est la suivante:
routeur:
R1(config)# interface fastEthernet 0/0
R1(config-if)# ip address 200.0.0.1
R1(config-if)# exit

R1(config)# interface fastEthernet 0/0.2
R1(config-sub)# encapsulation dot1q
R1(config-sub)# ip address 10.0.0.1
R1(config-sub)# exit

R1(config)# interface fastEthernet 0/0.3
R1(config-sub)# encapsulation dot1q
R1(config-sub)# ip address 172.16.0.1
R1(config-sub)# exit

R1(config)# interface fastEthernet 0/0.4
R1(config-sub)# encapsulation dot1q
R1(config-sub)# ip address 192.168.0.1
R1(config-sub)# exit
