PPP OverviewPPP Overview 100

PPP is the successor of this protocol which helped solve remote Internet connectivity problems in the late 1980’s

A: What is SLIP (Serial Line Internet Protocol)?

PPP OverviewPPP Overview200

A: What are Synchronous and Asynchronous?

Provides router-to-router and host-to-network connections over these circuits

S2C04 Jeopardy Review

PPP OverviewPPP Overview300

A: What is a Router?

Uses this device to provide a reliable connection

S2C04 Jeopardy Review

PPP OverviewPPP Overview400

A: What are Data Links?

PPP services are used to control and establish these

PPP OverviewPPP Overview500

A: What is the Data Link Layer (Layer 2)?

It operates at this OSI layer

S2C04 Jeopardy Review

PPP ComponentsPPP Components100

A: What are HDLC, LCP, and NCP?

The three (3) main components of PPP

S2C04 Jeopardy Review

PPP ComponentsPPP Components 200

A: What is LCP (link control protocol)?

The component that establishes, configures, and tests the data-link or WAN connection

S2C04 Jeopardy Review

PPP ComponentsPPP Components 300

A: What is NCP (network control protocol)?

It uses this to establish and configure network layer protocols, like IP, IPX, and Appletalk

PPP ComponentsPPP Components 400

A: What are Flag, Address, Control, Protocol, Data, and FCS?

The fields of a PPP Frame

S2C04 Jeopardy Review

PPP ComponentsPPP Components 500

A: What are Flags?

This field indicates the beginning or end of a frame

S2C04 Jeopardy Review

Session Establishment100

A: What are 1) Link establishment and configuration negotiation, 2) Link-quality determination, 3) Network layer protocol configuration negotiation, and 4) Link termination?

The four (4) phases

S2C04 Jeopardy Review

Session Establishment 200

A: What is the Network layer protocol phase (Phase 3)?

Datagrams are actually sent after this phase

S2C04 Jeopardy Review

Session Establishment 300

A: What are LCP packets?

These are sent in phase 1 (the link establishment and configuration phase)

S2C04 Jeopardy Review

Session Establishment 400

A: What are NCP packets?

These are used to configure network-layer protocols in phase 3

S2C04 Jeopardy Review

Session Establishment 500

A: What is a physical event like the loss of carrier or timeout?

This would cause the PPP link to terminate

S2C04 Jeopardy Review

PPP Authentication100

A: What are PAP and CHAP?

The two authentication methods supported by PPP

S2C04 Jeopardy Review

PPP Authentication 200

A: What is plain text?

PAP sends passwords as this

S2C04 Jeopardy Review

PPP Authentication 300

A: What is PAP?

Username/password is sent repeatedly until authentication is acknowledged or connection is terminated

S2C04 Jeopardy Review

PPP Authentication 400

A: What is PAP and CHAP?

This one uses two-way handshaking and this one three-way handshaking

S2C04 Jeopardy Review

PPP Authentication 500

A: What is CHAP?

Doesn’t allow the caller to attempt authentication without a challenge

S2C04 Jeopardy Review

Router Commands 100

A: What is Router(config-if)#username <name> password <password>?

Command to define the username and password to expect from the remote router

S2C04 Jeopardy Review

Router Commands 200

A: What is Router(config-if)#encapsulation ppp?

Command to configure the interface for PPP encapsulation

S2C04 Jeopardy Review

Router Commands 300

A: What is Router(config-if)#ppp authentication {chap | chap papa | pap pap | pap}?

Command to configure PPP authentication

S2C04 Jeopardy Review

Router Commands 400

A: What is Router(config-if)#ppp pap sent-username <username> password <password>?

In Cisco IOS Release 11.1 or later, you must enable PAP on the interface

S2C04 Jeopardy Review

Router Commands 500

A: What is Router(config-if)#ppp chap hostname <hostname>?

Can make remote users think they are connecting to the same router when authenticating by configuring the same hostname on each router
