Thanks. We'll let you know when a new response is added.

Can you provide the IP address statement you are trying to use together with the configuration of the VLAN interface IOS is reporting you are overlapping with.

Basically the error message is telling you that you are doing something wrong in configuration.

As an example you cannot configure vlan 1 with an ip address of 1.1.1.1/24 and then vlan 2 with an ip address of 1.1.1.2/24 as they are in the same subnet.
