Hello, I'm trying to configura simple VLAN in packet Tracer, In my company we have a rooter 2811 and a switch 2960 Catalyst 48TT.
In the packet tracer I use 2811 and 2960 24 TT and 2 PC's, I try to configure 2 vlan's vlan 10 use the port 5 in wtich is conected the PC0 and vlan 20 the port 6 in switch with PC1, The rooter is conected to the switch throught the 2 fastethernet lines to the switch gigabitethernet ports. Both PC's have an DHCP request failed. I hope somebody can explein me what I'm not doing well. I'm attach the packet tracer file.
This is the roote configuration:
enable
conf t
host R1
int fa0/0
no shut
int fa0/0.1
encapsulation dot1q 10
ip add 192.168.0.1 255.255.255.0
no shut
exit
int fa0/0.2
encapsulation dot1q 20
ip add 192.168.1.1 255.255.255.0
no shut
exit
ip dhcp pool IP10
net 192.168.0.0 255.255.255.0
default 192.168.0.1
exit
ip dhcp exc 192.168.0.1 192.168.0.10
ip dhcp pool IP20
net 192.168.1.0 255.255.255.0
default 192.168.1.1
exit
ip dhcp exc 192.168.1.1 192.168.1.10
exit
copy run start
sh ru
exit
This is the switch conf:
enable
vlan database
vlan 10 name 10
vlan 20 name 20
exit
configure t
interface fast 0/5
switchport access vlan 10
end
inter fa 0/6
switchport access vlan 20
end
write memory

Hello Eduardo,
the switch interface connecting to the router has to be configured as an 802.1Q trunk
int f0/x
switchport
switchport trunk enc dot1q
switchport mode trunk
Hope to help

I think maybe
"switchport trunk enc dot1q" command will not work.
So, you can run only this command "switchport mode trunk"
