I need an explanation for this Computer Science question to help me study.
Overview
Chapter 11 of the eText covers the deployment of IPv6. This lab demonstrates how to find detailed information about the IPv4 and IPv6 routing tables.
Instructions
This is the Module 11 Hands-On Project 11-1: Explore Route Servers from the MindTap.
Description: In this project, you log into a live route server hosted by a tier 1 service provider. You will run several show commands to get current information about the Internet routing.
Most ISPs offer public route servers. These are used by network engineers at customer sites and ISPs for troubleshooting and generic information. Most route servers for internal use are Linux- based servers, so the route information exists in text files and can be easily manipulated with scripts to create reports or track changes in various routes over time. External route servers like the one you will use are usually router-based. You can find a list of publicly accessible route servers at BGP Looking Glasses for IPv4/IPv6, Traceroute & BGP Route Servers (scroll down the page for the list of route servers) and another at traceroute.org. If, for any reason, the specific route server used in Hands-On Project 11-1 is unavailable, choose another route server from one of these Web sites. Note that the commands in this project are for the Juniper Junos operating system. Other route servers might use Cisco IOS or another operating system, and the commands may vary.
Open a command prompt window in Windows (click Start and type cmd in the Start menu search box, or enter cmd in the Search box on the task bar, then click cmd.exe in the resulting list) or start a Telnet client and telnet to route-server.ip.att.net. From the Windows command prompt, do this by typing telnet route-server.ip.att.net.
If youre running Windows 7 or Windows 10 and need to enable the Telnet client, click Start > Control Panel (in Windows 7) or right-click Start and select Control Panel (in Windows 10). Click Programs and then click Programs and Features. In the left pane, click the Turn Windows features on or off
link
. Scroll down and check the Telnet Client
checkbox
. Click OK. You can also install the Telnet client from a command prompt in Windows 7 or Windows 10 by issuing the following command:
pkgmgr
/
iu
:TelnetClient.
Follow the on-screen instructions for logging in. At the time of this writing, the username and password are both
rviews
. Notice the IPv4 and IPv6 routers and their addresses in the route servers network. The route-server> prompt appears at the bottom of the list.
Type show route summary and press Enter. Study the output, which displays the number of routes by type for every table.
Type show route extensive and press Enter. Press Enter several times to display more entries. Study the output, which shows much more detail than the route summary. Note that the AS path entry in the BGP section is a list of ASNs that the route traveled through to reach this server. Also, note the output can be hundreds of pages long and displays thousands of routes. Press q to stop scrolling.
Type show route table inet.0 and press Enter. Press Enter several more times to display more entries. Study the output, which shows the global routing table for IPv4 unicast routes. Press q to stop scrolling.
Type show route table inet6.0 and press Enter. Press Enter several more times to display more entries. Study the output, which shows the global routing table for IPv6 unicast routes. Press q to stop scrolling.
Type show
bgp
summary and press Enter. Press Enter several times to display more entries. Study the output, which displays BGP summary information for all routing instances. Press q to stop scrolling.
Wait about one minute and then repeat Step 7. Compare the rate of change in the table versions. Is the IPv4 or Pv6 table changing more often? Which do you think will be changing faster five years from now? Ten years from now?
Type show? to see a list of other show commands you can execute on this route server. Feel free to explore.
