Cisco 3750 Inter-VLAN routing / forwarding issue

[rustyknutz]

I have an upstream Adtran router with 802.1q trunking defined on a switchport that is connected to a Cisco 3750 also setup with trunking and 802.1q. Trunk shows up and forwarding all VLANs. However, when attemtpting to simply ping from the Netvanta to the Cisco's VLAN12 it times out. I can ping ip's within VLAN11 (which has an IP address configured on the Adtran) but not VLAN 12. VLAN12 is enabled on the Netvanta. I know there is something trivial I am missing, but I can't find it for the life of me.

Found the issue. Forgot to route VLAN12 traffic to the Cisco. What an idiot I can be sometimes.
