PT: IP Address OVERLAPS or Bad Mask

[SchwabVang]

I've successfully created a sub-interface for VLAN10 but when I try to create one for VLAN20 I keep getting a "BAD MASK" message or "IP ADDRESS OVERLAPPING".  I may be getting the words twisted up from my professor but I am having issues with assigning an IP to the sub-interface.  Any help or tips with this?

Hi @SchwabVang 

Zip your exercise (winzip) and attach it to check.

Meanwhile, you can verify that you are not assigning a network IP address on the interface, remembering that you must assign a host IP on the interfaces, within the corresponding network.
