Implementing Distance-vector routing protocol?
First you must decide what specific protocol you want to use. Then you configure it on the individual routers. Example, with Cisco routers: Router(config)#router rip Router(config-router)#network 10.0.0.0. Router(config-router)#exit Additional commands may be required for optimization. Note: I use RIP for illustration purposes, but it is usually not the best option for routing.First you must decide what specific protocol you want to use.

Which three statement are true regarding the encapsulation an de-encapsulation of packets when traveling through a router?
** The router modifies the TTL field, decrementing it by one.** The router maintains the same source and destination IP.** The router changes the source physical address to the physical address of the exit interface
How do you forward ports on routers and when and why?
To forward ports on your router just login to your router's on-line interface. Port Fowarding is used when a program (lets use FileFind [not a real program]) requests a port the router doesn't understand. Lets say that FileFind requests port 130 on your router, but your router doesn't have a port 130. It does, however, have a 128. The port forwarding tells the request to port 130 to be routed through port 128.

What router prompt can you use the router rip command?
On a cisco router you would go into privilege-exec mode (enable) and then into "configure terminal" mode. From there you can use the router rip command.
What does the enable command do in a cisco router?
The "enable" command will bring the privilege level from user exec to privileged exec. Example: R1> R1>enable R1#
What command is used to enter the routers privileged mode?
enable after the Router> prompt
While configuring a router network technician wants to name a router Which prompt the technician would see when entering hostname command?

Why can users establish a console connection to this router without entering a password?
The login command was not entered on the console line. The enable password should be an enable secret password. No username and password combination has been configured. Console connections cannot be configured to require users to provide passwords
A network administrator enters the service password-encryption command into the configuration mode of a router What does this command accomplish?
This command enables a strong encryption algorithm for the enable secret password command.
Which router configuration mode will require user authentification if an administrator issues the enable secret command?
It is the privilege mode.
What prompt can you issue show commands to investigate a Cisco Router?
