An alternative name for a Router is a Gateway.“Remote” refers to a destination device that is not directly attached tothe same network segment as the source device.The source device cannot send IP packets directly to the destinationdevice because it is in a different network segment. Instead you configureit to send the packets to a router which is attached to multiple segments.When it receives the IP packets, the router determines the next networkhop on the path to the remote destination, and sends the packets to thathop. This could either be the remote destination or another router closertowards the destination.dua1611-5aaa04.book Page 29 Friday, November 29, 2002 8:56 PM
