Getting a "Bad mask" error in your Cisco config can be frustrating, especially if copying a working configuation to a router running IOS 11.x  Here's how I answered a student's question after a Cisco class.

Question:

R5# conf t

R5( config )#int bri0

R5( config-if)#ip address 192.168.200.0 255.255.255.252

R5( config-if )#end

R5#
