| <para>The following steps show how a Cisco 3750 is configured for zone-level layer-3 switching. |
| These steps assume VLAN 201 is used to route untagged private IPs for pod 1, and pod 1’s layer-2 |
| switch is connected to GigabitEthernet1/0/1.</para> |

| <para>Setting VTP mode to transparent allows us to utilize VLAN IDs above 1000. Since we only |
| use VLANs up to 999, vtp transparent mode is not strictly required.</para> |
