ICND2 – PPPoE Questions

March 23rd, 2017 in ICND2 200-105 Go to comments

Question 1

Explanation

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

Question 2

Explanation

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 4

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

    Q3. Which command do you enter to enable an interface to support PPPoE on a client?

    Answer is:
    B. Dev1(config-if)# pppoe-client dial-pool-number 1

    pppoe-client dial-pool-number interface subcommand is used to add the interface to the same pool number configured on the dailer interface.

    pppoe enable subcommand is used to enable PPPoE on the interface.

    With command pppoe-client dial-pool-number 1 you add interface to the same pool number like dialer, but you enable ppoe too. After this one command is not necessary use ppoe enable (i think that IOS add this command to the running conf).
    Cisco question 🙁

    Once you add ‘pppoe-client dial-pool-number 1’ to the physical interface, IOS automatically adds ‘pppoe enable’ to the interface also.

    Is Q2 really on the exam because the objectives explicitly state client side. The instructor of my training videos mentioned that we don’t need to know the server side for the CCNA exam….server side is for CCIE not even CCNP. This kind of stuff drives me nuts because then you think what else is there in the dark. 🙁

    @Sebi, yeah, it is. I have no way to know if it was a “diagnostic question” for Cisco’s eyes only, but I had it.

    Your answer its incorrect because Configuring the ip address command within a virtual template is not recommended. Configuring a specific IP address in a virtual template can result in the establishment of erroneous routes and the loss of IP packets.
