Bad mask

[lucad7846]

Hi Everyone

I am trying to complete a PKT activity for an assessment. I need to configure a couple of VLAN's and I have been provided a table with all the details. 

When I try to set the IP address as per the provided table I get an this error message bad mask /24 for address 192.168.202.0

I may be wrong, but I think this could be related to the valid range of addresses. 

I think I am going to have the same issue with the other addresses on the table. How would I fix this? 

Please see screenshot attached. 

Many thanks in advance

the address you are trying to enter is network address. it cannot use for hosts or interfaces. you can use IP from 192.168.202.1 - 254.

your guide may explain which ip is need to configure to router interface.
