Hello,

I have new service from AT&T which they state is sending untagged traffic to all my new ports.

 At my central office I have a 2821 with an interface configured like this:

interface GigabitEthernet0/1/0
 description (Fiber connection to HFE/
 no ip address
 negotiation auto
!
interface GigabitEthernet0/1/0.1
 encapsulation dot1Q 20
 ip address 172.16.5.1 255.255.255.0
!
interface GigabitEthernet0/1/0.2
 encapsulation dot1Q 10 native
 ip address 172.16.2.1 255.255.255.0

At the remote sites I've tried tagging the interface for Vlan# but it doesn't seem to matter.  What does work is which ever side I set for "Native".  So router2 let's say had an interface configured for 172.16.2.2 it's running along no problem.

router3 172.16.5.2 doesn't get any traffic.

I know I am missing something.  Please talk to me like I am 5 because I am just a lone ranger on this one without a smartnet contract.

Thank you so much in advance!
