RESULT:

Note that first router table for remote networks was formed by RIP and when IGRP is enabled the new routing table or the information about remote networks to respective router is gathered by IGRP.

It is due the administrative distance of IGRP i.e. 100 which less than that of RIP i.e. 120.

Traceroute Command:

Traceroute works by sending packets with low time to live (TTL) fields. the TTL specifies how many hops the packet is allowed before it is returned. When a packet can't reach it's destination because the TTL value is too low, the last host returns the packet and identifies itself. By sending the series of packets and incrementing the TTL value with each successive packet, Traceroute finds out who all the intermediary hosts are. Traceroute is used to find the quality of internet connection.

The cmd is used as: tracert yahoo.com

Depending on the ms values displayed after the processing of the cmd, the latency is found and the quality is determined.

What is an ISDN?

http://www.networktutorials.info/index.html

ISDN network is a digital communication system that is capable of producing the maximum transmission speed of 1.4Mbps. 128Kbps speed is however more common in the digital technology. It's a international standard for sending data, voice, video over regular digital telephone lines. ISDN uses UTP (unshielded twisted pair cable) for transmission.

Types of ISDN NetworkThere are two basic types • Basic Rate Interface (BRI) – It consists of two 64 B-channels and one D-channel for transmitting control information.• Primary Rate Interface (PRI) -- It consists of 23 B-channels and one D-channel (for U.S.) or 30 B-channels and one D-channel (for Europe). The actual version of ISDN employs base band transmission. Another version, called B-ISDN, uses broadband transmission, which is able to support transmission rate of 1.5 Mbps. B-ISDN mainly requires fiber optic cables. To access the B channel, it is necessary to subscribe the ISDN phone line. Customers are also required to have some special ISDN devices, which are known as terminal adapters, which are used to communication with the telephone company switch or other ISDN devices.

http://www.webopedia.com

SPID:

Service Profile Identifier, a number that identifies a specific ISDN line. When you obtain ISDN service, your telephone company assigns a SPID to your line. Part of the initialization procedure is to configure your ISDN terminal adapter to use this SPID.

Most telephone companies in the U.S. use the Generic SPID Format, which is a 14-digit number. The first 10 digits identify the telephone number, called the Directory Number (DN). The remaining four digits identify a particular ISDN device, in the case where multiple devices share the same Directory Number.

What is Telnet?

http://www.apluskb.com/scripts/category_1pp196.html

As a common way to remotely control a web server, Telnet is a protocol for remote computing on the Internet. It allows a computer to act as a remote terminal on another machine, anywhere on the Internet. This means that when you telnet to a particular host and port, the remote computer (which must have a Telnet server) accepts input directly from your computer (which must have a Telnet client) and output for your session is directed to your screen. There are many library and information resources that are accessible through Telnet.

SearchNetworking.com

Telnet is a user command and an underlying TCP/IP protocol for accessing remote computers. Through Telnet, an administrator or another user can access someone else's computer remotely. On the Web, HTTP and FTP protocols allow you to request specific files from remote computers, but not to actually be logged on as a user of that computer. With Telnet, you log on as a regular user with whatever privileges you may have been granted to the specific application and data on that computer. A Telnet command request looks like this (the computer name is made-up): telnet the.libraryat.whatis.edu The result of this request would be an invitation to log on with a userid and a prompt for a password. If accepted, you would be logged on like any user who used this computer every day. Telnet is most likely to be used by program developers and anyone who has a need to use specific applications or data located at a particular host computer.
