401notfound not have long to give an article about Cisco, on occasion this time I will explain about the Administrative Distance, Administrative Distance is a numeric value that specifies the preference of a particular route, It's a calculated value used to determine the best path to a destination, each routing protocol has an administrative distance separately. In the example above picture there are EIGRP and RIP protocols , when a PC with a network 192.168.3.0/24 to send packets to the 192.168.6.0/24 network packet routing who to use is EIGRP will pass this is because the Administrative distance is smaller than the Administrative Distance to the RIP.

Cisco corporation has launched a new series of packet tracer it is packet tracer 5.2, the latest version of this excess is the addition of a laptop that can feature in the system configure VPN, VPN (Virtual Private Network) is a private network to connect remote-site between safely. VPN is divided in two parts ie part of the system is protected by certain passwords and the outside of the internet infrastructure is not protected.
