Cisco CISCO3725 3725 2-Slot Multiservice Access Router

all right so here we are just about to start playing with Sisko to some basic IP stuff I've got three Cisco rooters here they are all Cisco 3725 with appropriate iOS's load we'll see that a little bit later we can see I've got the laptop PC up the top right that's being used to interrogate currently it's connected to the same subnet as root 2a it's fast ethernet port fastethernet 0/0 as indicated by the port up here at the top this little bubble on the side which has got dot one side which is part of its IP address that IP address is part of the subnet we can see the subnet to which route or a is connected to through this interface that subnet is 192.168.20.10 or we can see that because the house so at another device connected to the same network all of those devices must have the same mask and this indeed does it has a different IP address of course but on the same subnet so 192.168.20
