Hi thanks for the replay. *for Vlan 1,i use :* Cisco 3500xl : interface FastEthernet0/1 switchport trunk encapsulation dot1q switchport mode trunk interface FastEthernet0/4 switchport trunk encapsulation dot1q switchport mode trunk interface VLAN1 ip address 10.0.202.1 255.255.255.0 no ip directed-broadcast no ip route-cache then i have to PC's for example, Windows and Linux box. Windows Box : 10.0.202.5/24 Linux Box( Router ): modprobe 8021q vconfig add eth0 1 ifconfig eth0.1 10.0.202.254 netmask 255.255.255.0 up 10.0.202.254/24 both connected on int 1 and 4. If i try to ping i get destination host unreachable.* for Vlan 5 ,i use :* Cisco 3500xl : interface FastEthernet0/2 switchport access vlan 5 interface FastEthernet0/5 switchport access vlan 5 then i have to PC's for example, Windows and Linux box. Windows Box : 10.2.100.1/16 Linux Box(Router): modprobe 8021q vconfig add eth0 5 ifconfig eth0.5 10.1.100.2 netmask 255.255.0.0 up 10.2.100.2/16 the problem is that i can?t communicated while trieing VLan 1 . you have any ideas ?
