As an administrative network is of course we must know the network topology by the routing table to see the only form of letters and numbers only, of course this is a problem that exists for a junior admin, will teach here sonny see topology of the routing table, consider the well
Every time the Cisco router is turned on, this equipment will perform a routine process that is called the boot process, the boot process is working through a specific sequence as follows:
- First the router will run the Power On Self Test (POST) to check the CPU, memory and interface equipment to ensure that the router hardware to function properly.
- Then bootstrap the system will work for a Cisco IOS image that can be used. Generally this Cisco IOS image can be obtained from flash memory or from the tftp server, depending on the configuration list is used by the equipment. By default this configuration register value 0x2102 which will tell the router to find the IOS image from flash memory.
- IOS image search efforts conducted 5 times, if not successful, the router will enter ROM mode to enable the IOS image manually.
- If the IOS image found, the IOS image will be loaded into RAM memory system
- Then, the router will look for first configuration (start-up configuration) which is generally found in NVRAM
- If the router is turned on for the first time, the router has yet to have a first configuration, and the router will run the system configuration dialog that allows the creation of first configuration manually.
- ROM allows you to save a bootstrap system that serves to regulate the boot process and run the Power on Self Test (POST) and the IOS image
- NVRAM configuration store that served the initial (start-up configuration)
- RAM which has the task to save the running configuration (running configuration) and Cisco IOS operating systems are active.
- FLASH useful to store the IOS image, using FLASH, a new version of IOS can be obtained from the TFTP server without having to replace components in the router.

NVU is a web application editor is "what you see is what you get". Someone can make a web designer with no advanced syntax syntax-HTML tags. This application has the advantage of them: You can directly upload web pages Amda built into your web hosting on the Internet, using the facilities manager's ftp site NVU, NVU is a standalone tool, yangtidak tied with other applications, many colors, dilegkapi css editor, can directly open and edit an existing web page on the Internet and then upload them, for a programmer nvu equipped with a tool to insert php code and javascript.
Getting NVU http://www.Nvu.com/download.php
I. Instalasi NVU di linux
If you have nvu in the form of rpm, then the way to type the command installation
# rpm –i nvu-x.x-x.rpm
If you use linux distro redhat variant, denngan orders
# alien –i nvu-x.x-x.rpm
If you use linux distro debian or knoppix variant
# dpkg –i nvu-x.x-x.deb
Whereas if you get nvu in bz2 tarball, eg, nvu-1.0-pc-linux2.6.10-gnu.tar.bz2, then you need to decompress the file first with the command:
# bunzip nvu-1.0-pc-linux2.6.10-gnu.tar.bz2
or
# bzip2 nvu-1.0-pc-linux2.6.10-gnu.tar.bz2
end then
# tar xf nvu-1.0-pc-linux2.6.10-gnu.tar
After going through these roses, will be formed direktorinvu-1.0 which contains all the components nvu program.
$ Nvu
but if you had installed in the form of tar bz2, then to run Nvu by going to the directory where the extracted eg nvu xsrc/nvu1.1
$ xsrc/nvu1.1
$ sh nvu

1. first router snapshot
Router>ena
Router#conf t
Router(config)#hostname R1 -- in here i gift name to router is R1
R1 (config)#int fa0/0 --sync fastethernet
R1 (config-if)#ip address 192.168.1.17 255.255.255.240

R1 (config)#int ser2/0
R1 (config-if)#ip address 20.1.1.1 255.255.255.252
R1 (config-if)#clock rate 64000 --clock rate to using if in int ser any watch picture
R1 (config-if)#no shutdown
R1 (config-if)#exit
Configuration is completed on the first router, make almost the same thing also on the second router.
After its completion when we configure ip route to network with each other network can be connected.
R1(config)#ip route net-tujuan sub-tujuan next_hoop
R1(config)#ip route 192.168.2.24 255.255.255.248 20.1.1.2
R1#copy running-config startup-config --this is done so that if the router is switched off the previous configuration is not lost
Also in the router do next. Okey... ..
Rich I am not sure you are doing okay I am biased configuration guided
2. in 2nd Router
Router1>ena
Router#conf t
Router(config)#hostname R2
R2(config)#int fa0/0
R2 (config-if)#ip address 192.168.2.25 255.255.255.248
R2 (config-if)#no shutdown

what if there are 3 routers?? very different indeed if we want to route router0 (R1) to router2 (R3) here next_hoop (door) is ip address of the router, the URLs R1 as the postman will visit with an escort home, R2 as security (guards), R3 as host. Then R1 here of course can not directly go into the house and met his host, but spoke first to the security, saying "no mas master at home??" And the guard into the house and said to his master, "the lord is the postman .." " grab the package "the master said that the analogy ..
so if you want to route R1 (router0) to R3 (router2), next_hoop used next_hoop on R2 serial2 / 0
Finished configuring the router, now 2 men sharing each other network to do things hhe, good luck!!. /febtian
