Hello,
I am creating subnets to be used for a small office and I am getting the error, "Bad mask /26 for address 10.23.140.128"for example. I want to create 4 x 64 address subnets starting with 10.23.140.0. The first interface used "ip address 10.23.140.1 255.255.255.192" and it worked. Subsequent interfaces used " ip address 10.23.140.64 255.255.255.192" and so on, and they give the error. where am I going wrong? Working on a Cisco Catalyst 3560.
Thanks.
