ACKNOWLEDGEMENT

We can write a 1000 page book, but we can’t find enough words to describe the
credit Mr. Siddiq Ahmed deserves for what is good about this book. Your ability to guide
us made the toughest things easy in developing this book. We still refuse to write a book
unless you develop it!!

Behind the scenes at Netmetrics is a vast array of talented people – all of whom
made it possible to develop the book. People, who provided the right equipment in the
right time, people who maintained a friendly atmosphere to finish the work in time. Many
thanks to you all for the hard and good work.

Thanks to Nizam, Anwar, Afsar, Awadh, Sreenivas and Mr. Prasad for finding
better ways to describe how the technical pieces fit together, for fixing errors.

Thanks to Mr. Abdur Rahman for giving us the time we needed to work on this
book and by making sure the job was fun.

Finally, no acknowledgement section could be complete without acknowledging
ourselves, who took all the responsibility and dedication in completing the book.

Finally, to GOD, who gives us strength when things are tough, and peace beyond
belief – THANK YOU!!!

The output displays net 20.0.0.0 as ‘O’ and net 2.0.0.0 as ‘O IA’, but there is no net
30.0.0.0, as it is not connected to area0.

We need to configure virtual links between R2 & R3 and this area that connects to area0
is called the transit area.

Each router R2 & R3 point at the router-id of the other router.

Task 2:

Configure Virtual Link between R2 and R3:

the router1 assumes that net 30.0.0.0 is in the same area0.
