How to Configure Static Routing on Cisco Routers
August 16th, 2010
Cisco IOS Routers support both static and dynamic routes. In small networks (2 to 5 routers) I would suggest to configure only static routes, especially if the network is not going to change much over time. Of course dynamic routing (using dynamic routing protocols such as RIP, OSPF, EIGRP) is much more flexible and scalable (for larger networks) but gets a little bit tricky to troubleshoot in case of problems. There is also the option to mix static and dynamic routing if needed, but you need to take into consideration issues such as route redistribution (you will usually need to redistribute static routes into the dynamic protocol).
In this post I will try to illustrate static routing using a small network scenario (see picture below) and explain also some other issues related with ICMP Redirects and Cisco ASA firewall.
Network Description
From the example network above, we have a Cisco ASA firewall (ASA1) protecting our internal networks from the Internet.

Career advice: Training on the cheap

Ask a Premier 100 IT Leader Jim Fortner
Title:
Vice president
Company: Procter & Gamble
Fortner is this month’s Premier 100 IT Leader, answering questions about training on the cheap, giving input to a nontechnical boss, and the merits of switching employers. If you have a question you’d like to pose to one of our Premier 100 IT Leaders, send it to askaleader@computerworld.com.
The company I work for used to be very generous about training, but it has cut back severely. But I can’t do it on my own, what with taking a pay reduction and working longer hours after layoffs. I don’t want to be left behind in skills. What can I do? It is absolutely critical that you continue to invest in yourself to remain relevant in your business. Do not let your company’s lack of funds be a barrier to advancing your career.
There are four types of training that do not cost much. The first of these can be found on the Web. Many of the offerings there present opportunities for real skills building.

The Importance of IT Training
Information Technology is a booming industry. For an individual who decided to get into this field, it will be a rewarding decision in terms of salary compensation but also quite a challenge too. Attending a focused and high quality I.T training related to your profession is inevitable if you want to survive in the demanding I.T career. Moreover, if this IT Training will help you also to obtain an I.T certification, this is even better. A certification in I.T (e.g certification in Microsoft, Cisco, VMWare, CompTIA etc) will help you tremendously to become established as an expert in the industry and will show also your current or prospective employer that you are investing in your career and that you are a person who takes his/her career advancement seriously.
IT Training Options
There are several options for getting an I.T Training. You can buy books and study by yourself (the cheapest option), you can attend a classroom/instructor based training (most expensive option), or you can purchase a Computer Based video training (probably the best option).
