If you are not sure about PPPoE, please read our PPPoE tutorial (on digitaltut.com).

Question 1


The picture below shows all configuration needed for PPPoE:


There is no Dialer interface on the PPPoE Server so answer “Dialer interface” is not correct. The most suitable answer is “Virtual Template” interface as it contains the pool which is used to assign IP address to the PPPoE Client. But this question is weird because according to the CCNAv3 syllabus, candidates only need to grasp the PPPoE on client-side, not sure why this question asked about PPPoE on Server side. For more information about PPPoE, please read our PPPoE tutorial.

Question 2


PPPoE provides a standard method of employing the authentication methods of the Point-to-Point Protocol (PPP) over an Ethernet network. When used by ISPs, PPPoE allows authenticated assignment of IP addresses. In this type of implementation, the PPPoE client and server are interconnected by Layer 2 bridging protocols running over a DSL or other broadband connection.

PPPoE is composed of two main phases:
+ Active Discovery Phase: In this phase, the PPPoE client locates a PPPoE server, called an access concentrator. During this phase, a Session ID is assigned and the PPPoE layer is established.
+ PPP Session Phase: In this phase, PPP options are negotiated and authentication is performed. Once the link setup is completed, PPPoE functions as a Layer 2 encapsulation method, allowing data to be transferred over the PPP link within PPPoE headers.

Question 3


In the Dialer interface, we can use the “ip address negotiated” command to ask for an IP address from the PPPoE Server.

    Hi Friends!
    I really confused with this question:

    Which two facts must you take into account when you deploy PPPoE. (Choose two.)

    A. DDR idle timers must be configured to support VPDN logging

    B . DDR is not supported

    C . You must manually configure IP addresses on the PPPoE interface

    D . PPPoE supports a maximum of 10 clients per customer premises equipment

    E . An individual PVC can support one PPPoE client

    After I learned the PPPoE configuration topic, I still don’t understand what is correct answer. When I check in 4 different dumps – I see 4 different answers!!!

    But I think – it DE.

    Thank you!
