How is PPP used for WAN connectivity?

Last Updated: 16th March, 2020

A point-to-point connection is one of the most common types of WAN connection. PPP connections are used to connect LANs to service provider WANs, and to connect LAN segments within an organization network.

Consequently, what is PPP networking?

In computer networking, Point-to-Point Protocol (PPP) is a data link layer (layer 2) communications protocol between two routers directly without any host or any other networking in between. It can provide connection authentication, transmission encryption, and compression.

Similarly, what are the three phases to establishing a PPP session? The PPP session establishment has three phases. The first step (phase) in PPP session establishment is Link Establisment where LCP packets are sent. The second phase, Authentication Phase, is optional. PPP supports CHAP and PAP authentication protocols.

In this way, what is the use of PPP protocol?

Point - to - Point Protocol (PPP) is a communication protocol of the data link layer that is used to transmit multiprotocol data between two directly connected (point-to-point) computers. Since it is a data link layer protocol, data is transmitted in frames. It is also known as RFC 1661.

What is a WAN link?

WAN link is a communication circuit that joins two or more local area networks (LANs) into a wide area network (WAN).

How do I configure PPP?

Let's now configure R1 and R2 to establish a point-to-point serial link using PPP as the Layer 2 protocol.
  1. R1>enable. R1#configure terminal. Enter configuration commands, one per line.
  2. R1#show interfaces Serial1/0. Serial1/0 is up, line protocol is up.
  3. R1# R1#configure terminal.
  4. R1#show users. Line User Host(s) Idle Location.

What are the benefits of PPP?

PPP advantages:
  • Ensure the necessary investments into public sector and more effective public resources management;
  • Ensure higher quality and timely provision of public services;
  • Mostly investment projects are implemented in due terms and do not impose unforeseen public sectors extra expenditures;

How does PPP protocol work?

Point-to-Point Protocol or PPP is a layer 2 or data link layer protocol that is used to establish a direct connection between two nodes in a network. It can provide authentication, encryption, and compression. This protocol is used to create a simple link between two peers in a network to transport packets.

Why is PPP used?

PPP is a protocol most widely used by Internet service providers (ISPs) to enable dial up connections to the Internet. PPP facilitates the transmission of data packets between point to point links. Originally designed to work with serial connections, PPP was adopted by ISPs to provide dial up Internet access.

What is PPP username and password?

Point to Point Protocol over Ethernet (PPPoE) is a type of broadband connection that provides authentication (username and password) in addition to data transport. Most DSL providers use PPPoE to establish Internet connections for customers.

Where is ATM network used?

ATM is a core protocol used over the SONET/SDH backbone of the public switched telephone network (PSTN) and Integrated Services Digital Network (ISDN), but its use is declining in favour of all IP.

Where is TCP IP used?

TCP/IP, or the Transmission Control Protocol/Internet Protocol, is a suite of communication protocols used to interconnect network devices on the internet. TCP/IP can also be used as a communications protocol in a private network (an intranet or an extranet).

What are the key features of the Point to Point Protocol PPP )?

PPP has three main components: a way to encapsulate multiprotocol datagrams; a Link Control Protocol to establish, configure and test the data-link connection; and a group of network control protocols that establish and configure different types of network-layer protocols.

What is PPP and HDLC?

The major difference between HDLC and PPP is that HDLC is the bit oriented protocol, while PPP is the character-oriented protocol. The HDLC and PPP are the crucial data link layer protocols used in WAN (wide area network) where the HDLC can also be implemented with PPP for the efficient results.

Is PPP still used?

In an Ethernet services world, PPP has been relegated to primarily being used for PPPoE or PPPoA however many companies still use PPP for a lot of things. The beauty about PPP is it is not medium dependent. PPP provides features that are not present In the generic mediums, the most prevalent being authentication.

What is PPP and SLIP?

SLIP and PPP are the two distinct independent serial link encapsulation protocols. The significant difference between the SLIP and PPP is that SLIP is the earlier version protocol while PPP is the later variant which gives several advantages over SLIP such as detection and prevention of misconfiguration, etcetera.

Is PPP encrypted?

The PPP Protocol field of the encrypted datagram indicates that the frame is encrypted, but not the algorithm with which it was encrypted. The maximum length of an encrypted packet transmitted over a PPP link is the same as the maximum length of the Information field of a PPP encapsulated packet.

How does CHAP work?

CHAP is an authentication scheme used by Point-to-Point Protocol (PPP) servers to validate the identity of remote clients. The verification is based on a shared secret (such as the client's password). After the completion of the link establishment phase, the authenticator sends a "challenge" message to the peer.

Is PPP connection oriented?

PPP is a connection-oriented protocol that enables layer two links over a variety of different physical layer connections. It is supported on both synchronous and asynchronous lines, and can operate in half-duplex or full-duplex mode.

What are different types of WAN?

Wide Area Network (WAN) –
The technology is high speed and relatively expensive. There are two types of WAN: Switched WAN and Point-to-Point WAN. WAN is difficult to design and maintain. Similar to a MAN, the fault tolerance of a WAN is less and there is more congestion in the network.
