July 27th, 2017 in ROUTE 300-101 Go to comments

Question 1

Explanation

By default, EIGRP load-shares over four equal-cost paths. EIGRP also support unequal-cost load balancing via the “variance” command.

Question 2

Explanation

The table below lists the default administrative distance values of popular routing protocols:

Routing Protocols Default Administrative Distance
EIGRP 90
OSPF 110
RIP 120
eBGP 20
iBGP 200
Connected interface 0
Static route 1

Question 3

Question 4

Explanation

The following list of parameters must match between EIGRP neighbors in order to successfully establish neighbor relationships:

+ Autonomous System number.
+ K-Values.
+ If authentication is used both: the key number, the password, and the date/time the password is valid must match.
+ The neighbors must be on common subnet (all IGPs follow this rule).

Question 5

Explanation

When EIGRP is configured in a point-to-multipoint Frame Relay network, although the Hub can receive routing updates sent from its Spoke routers but split horizon rule forbids the Hub from relaying advertisements back out the interface on which they were received. For example in the topology below, Hub can receive routing updated from two Spokes but it cannot relay them out of S0/0 interface again (as it is the interface where it received the updates). To solve this problem we need to disable split horizon on S0/0 interface of Hub.

Frame_Relay_Point_to_multipoint.jpg

The command should be (suppose EIGRP 1 is running):

Hub(config)#interface serial0/0
Hub(config-if)#no ip split-horizon eigrp 1

Therefore answer A is correct.

In Non-broadcast networks (such as Frame-Relay), multicast (and broadcast) are not allowed while EIGRP (and OSPF, RIPv2) uses multicast to send Hello and Update messages. Therefore these dynamic routing protocols would not work well under Frame-Relay. To overcome this issue we usually add the keyword “broadcast” at the end of the frame-relay map statement (for example, “frame-relay map ip 10.1.1.1 403 broadcast“). This makes EIGRP to send update via unicast instead of multicast.

Another way to resolve above issue is to use the “neighbor” command. This command also make EIGRP to communicate with its neighbors via unicast -> B is correct.

Note: Although we can use the “neighbor” command to set up EIGRP neighbor relationship but the routes cannot be advertised from the Hub to the Spoke because of split horizon rule.

Question 6

Explanation

Although we can use the “neighbor” command to set up EIGRP neighbor relationship but the routes cannot be advertised from the Hub to the Spoke because of split horizon rule -> Answer D is not correct.

To overcome the split horizon rule we can use subinterface as each subinterface is treated like a separate physical interface so routing updates can be advertised back from Hub to Spokes.  -> Answer C is correct.

Note: The split horizon rule states that routes will not be advertised back out an interface in which they were received on

Question 7

Explanation

The “ip summary-address eigrp” command is used to configure interface-level address summarization. EIGRP summary routes are given an administrative distance value of 5. The administrative distance metric is used to advertise a summary without installing it in the routing table.

Question 8

Question 9

Explanation

An example of how to configure EIGRP authentication on two routers that are connected to each other is shown below:

R1,R2(config)#key chain MYKEYS
R1,R2(config-keychain)#key 1
R1,R2(config-keychain-key)#key-string SecRetThing!
R1,R2(config-keychain-key)#end

R1,R2(config)#interface serial 0/0
R1,R2(config-subif)#ip authentication mode eigrp 10 md5
R1,R2(config-subif)#ip authentication key-chain eigrp 10 MYKEYS

Question 10

Explanation

When redistributing into RIP, EIGRP (and IGRP) we need to specify the metrics or the redistributed routes would never be learned. In this case we need to configure like this:

router eigrp 1
redistribute ospf 100 metric 10000 100 255 1 1500

    Only 2 questions in eigrp? since eigrp has more topics, there should be many questions i guess.
    can anyone plz confirm?

    Hello Nine tut, and audience, is there a way that any body can display the questions and answers in full.
    Thank you very very much.

    Shouldnt the 1. question be A as an aswer? -> EIGRP allows a maximum of four paths across for load balancing traffic.

    Hi Gihan,

    I tried emailing you with gmail.com, but mail got failed.
    I will be much appreciate If you could share your dumps to my email localeanditservices@gmail_com (gmal.com – i mean).

    can anyone who has given the ccnp route exam recently share their experience.
    thanks

    All, I failed today with a 640. The ‘300-101: Implementing Cisco IP Routing’ exam is completely different then what is on this site. Not even close. There are maybe 10 questions that are the same… What happened???

    @ aboodnet

    You cannot see the questions because you need to pay for the premium subscripton in digitaltut.com :) is 10 dollars for 1 month.

    It is worthy.

    Which two options are requirements for EIGRP authentication? (Choose two)
    A. A crypto map must be configured.
    B. The Authentication key must be configured under the interface running EIGRP.
    C. The authentication key must be configured within the EIGRP routing configuration.
    D. The authentication key IDs must match between two neighbors.
    E. A separate key chain must be configured.
    F. AN IPsec profile must be configured.

    Ans: B,D.
    ‘B’ is not quite precise because de Auth Key is configured under the key chain.
    ‘D’ is tottaly true, the key ID is sent with the EIGRP packet and is used by the other side to identifies the key-string to use.
    ‘E’ is wrong because is not mandatory to configure an exclusive key chain for EIGRP, the same key-chain can be shared with RIPv2.

    Which command prevents routers from sending routing updates through a router interface?
    A. default-metric 0
    B. distribute-list in
    C. passive-interface
    D. distribute-list out

    Answer is suppose to be C passive-interface, but distribute-list in could also used? Thoughts?

  27. wint3r
    July 28th, 2017

    distribute-list out command is configured inside ospf configuration and it prevents routes from going out of OSPF routing protocol and is not specific to an interface.

    but a nice question though

    Question 3 must be: Time instead of password I think:

    Requirements
    The time must be properly configured on all routers. Refer to Configuring NTP for more information. For the authentication keychains with keys are used. The term password is not mentioned in the cisco documentation.

    Question 3 must be: Time instead of password

    I think the same….In other documents the answer is TIME.
