Sample configuration moving from to


We have Cisco 3560 switch within our network, which connects to the modem and from there it goes to the fibre network BT. This switch does the internet routing.

The IP subnet for our network at the moment is We will be running out of IP addresses very soon. Also we are going to expand our network with more devices coming into our LAN.

I am planning ask our network team allot me a new IP subnet and this will give me 4094 IP address.

I am not sure how this new IP subnet will be configured on the Cisco 3560 routing switch.

Will they delete the exiting and configure or a NATTING

I am interested to see a sample configuration. It will be really helpful for me to understand if I see a sample configuration.

Unfortunately it’s the Network team policy they are not allowed to show me the configuration.

Please, please help!!
