We are in the process of using AT&T's switched ethernet to transport. They're using a single VLAN tag to carry traffic from our 70 locations back to the core. I have a 4506 at the distribution and 6509 at the core.
To simply, I have an IP address on the VLAN that AT&T is tagging that is responsible for forwarding traffic. Using OSPF, I have the additional routes summarized that are associated with different VLANs. Here is the output.
Here's the problem, when I do a traceroute from a device that's on a different VLAN besides the vlan that's tagged on the AT&T ASE network, it fails. It's failing at the 4506 and never makes it to the Core at the Data Center b/c the default VLAN being used is not the tagged VLAN.
Of course, on the EIGRP network that uses AT&T managed services, I can traceroute and see hops to the core and then internet.
If you can shed some light on this, please let me know. Thanks. By the way, the routes are all learned and can be seen properly. I also noticed that I cannot telnet using the 3.3.3.x network unless I'm directly on the Core.
