A hub floods the network Together with the packet and only the location method gets that packet while some just drop as a result of which the site visitors raises a great deal. To solve this issue switch came into your

interface? I tried hunting around but all I found is loopback. I need another conclusion of the wire recognizes this as two interface, so loopback will not likely do it. Hypervisors like VMWare have an option to do just this (VM and host this site are identified as two equipment on router's arp desk), but in my scenario utilizing a VM is essentially overkill. I just want Yet another link, Or even some apps that could behave for a "Digital switch".
