Hi everybody,
I would like to create a q in q vlan inside my network architecture but unfortunately i have only to 2941 router to do this functionality. I find several websites which describe q in q vlan cisco commands.
Finally I do the below configuration in my two tunneling routers :
#R1
enable
conf t
no ip routing
interface GigabitEthernet 0/0
no shut
interface GigabitEthernet 0/1
no shut
interface GigabitEthernet0/0.100
encapsulation dot1q 100 second-dot1q 2,3
no shut
interface GigabitEthernet0/1.2
encapsulation dot1q 2
no shut
interface GigabitEthernet0/1.3
encapsulation dot1q 3
no shut
#R2
enable
conf t
no ip routing
interface GigabitEthernet 0/0
no shut
interface GigabitEthernet 0/1
no shut
interface GigabitEthernet0/0.100
encapsulation dot1q 100 second-dot1q 2,3
no shut
interface GigabitEthernet0/1.2
encapsulation dot1q 2
no shut
interface GigabitEthernet0/1.3
encapsulation dot1q 3
no shut

Hello,
the config looks about right. Since you cannot convert the GigabitEthernet interfaces to true layer 2 ports, you cannot use the 'switchport mode dot1q-tunnel' command.
