NAT CONFIGURATION

Routers Used: 2621 w/ CISCO2600-MB-2FE and WIC-2T modules IOS: c2600-i-mz.121-5.T9 Objective In this lab, Port Address Translation (PAT) and port forwarding are configured. Scenario The International Travel Agency is planning to launch an informational Web site on a local Webserver for the general public. However, the one Class C address that has been allocated will not be sufficient for the users and devices the company has on this network. Therefore, a network is configured that will allow all internal company users access to the Internet and all Internet users access to the company’s informational Web server through static NAT and PAT. Internal user addresses must be translated to one legal global address and all Internet Users must access the informational Web server through the one legal global address as well. Step 1 Build and configure the network according to the diagram. If you are using the configuration files from the previous lab, remove the NAT pool (public) and the stati...

CCIE EIGRP METRIC CALCULATION

One of the annoying fileds in my opinion is calculation, I hate them! in my mind it is just in the way of the cool stuff. but unfurtunetly to get to the cool stuf you need to calculate. so I would like to start by giving you a little review and may be more indepth look over EIGRP Metric, as we all should know EIGRP is a Hybrid Routing Protocol that use a Composite Metric in his DUAL Diffusing Update Algorithm. the Composite metric is composed (good word selection :-)!?) from K Values. K1 K2 K3 K4 K5 K1 = Bandwidth = 1 meaning it is used in the calculation by default. K2 = load = 0 you gust it, meaning that is not participating in the calculation by default. K3 = Delay = 1 you can take it from here K4 = Reliability = 0 K5 = MTU = 0 the K values tells us if the value is participating in the calculation or not and what is the weight of the value, meaning that if you set K1 to 3 then it means that the weight of K1 will be 3 times more "important" or in other words it will take th...
