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:
description (Fiber connection to HFE/
no ip address
encapsulation dot1Q 20
ip address 172.16.5.1 255.255.255.0
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!
