I have a class C that I want to better understand before I implement a change.
ip address 192.168.0.1 255.255.255.192 ip address 192.168.0.65 255.255.255.240 secondary
So, where is the 192.168.0.64 address in that mix? 192.168.0.63 should be the broadcast for the first one, and 192.168.0.65 should be the cisco secondary ip.
How then do I add a /28 (255.255.255.240) right before this segment:
ip address 192.168.0.249 255.255.255.248 secondary
In fact, I'll probably want to add it as a subinterface
Can anyone help me to better understand whats going on and then how to do it?
