BGP Questions

Focus on Question3 I dont think the answer is A I prefer to D rather than A Because The LOCAL_PREF attribute affects only traffic leaving the AS. To influence incoming traffic, the MULTI_EXIT_DISC attribute, known as the MED for short If you disagree please leave a comment
BestRegards

Meanwhile Unlike LOCAL_PREF, in which the largest value is preferred, the lowest MED value is preferred.

OH I am very sorry that i am confused with weight and MED
Yeah the answer is the A that is right
Please delete the comments before it…….

thanks for sharing

Note for Question 4 the correct answers is A & E. Answers A & F is wrong, If you see “State/PfxRcd” column :
10.1.1.1 state is 2 that means BGP session to the 10.1.1.1 neighbor is already established
10.3.3.3 state is idle. This means that neighbor is established, but the router has not received any BGP routing updates from the 10.3.3.3 neighbor.

Please digitaltut or anybody here correct me if im wrong. Or leave ur comments

@zak
look what write about IDLE:
1 – Idle: the initial state of a BGP connection. In this state, the BGP speaker is waiting for a BGP start event, generally either the establishment of a TCP connection or the re-establishment of a previous connection. Once the connection is established, BGP moves to the next state.
THIS NOT MEAN THAT neighbor is established its INITIAL STATE
SO A F IS RIGHT

now what the correct answer ?????????????????

If you’re confused, always trust digitaltut ;) BTW correct as AF

Hi Guys

I am preping for my MPLS 642-611 exam. Can someone please point me to the right directions for dumps / labs. I have old dumps but i have no idea how exam labs looks like. Any help will be great.

Thanks.

hey,

on question 6 in the question it sais both are originated locally, would the next test not be AS-path? (i know local pref was not mentioned in the question but knowing the twisted way Cisco like to trick us)

cheers

Taking Route Paper Tomorrow :)

I have made all of the 642-902 Test sims in a GNS3 format, just email if you want a copy at cciersbound@yahoo.com

Later,

hello jibran
no comment on u’r test
i mean 642-902 route test
pls say sthing related to the questions on this tut
or any body can help who took the exam recently
thanks

Hi All,
Can somebody send me the Q&A and labs came in the exam, if anyone can please help me out at noumanmian@yahoo.ca.

Just posted up my CCNP-Route BGP revision notes.

Hope you find them useful ^_^

Which BGP command provides the router ID, local preference, next hop, and BGP path in its output?

Is the answer –> Show IP BGP or
Show IP BGP Summary

Which BGP option is required when load sharing over multiple equal-bandwidth parallel links from a single CE router to a single ISP router over eBGP?
——————————–
A. eBGP Multipath
B. eBGP Multihop
C. BGP Synchronization
D. Public AS numbers

Some sites say Multipath and others have Multihop.

@Rodrick

I was a little confused too but after re-reading the cert book I noticed the use of loopback interfaces. So, in this configuration, one would have to use loopbacks forcing the use of the Multihop command

@Rodrick Burke
Use google, Luke

Correct answer is B

http://www.cisco.com/en/US/tech/tk365/technologies_configuration_example09186a00800945
bf.shtml

Can someone explain this answer? q92 from dodo
the suggested answer is B,C – doesn’t the suggested answers just re-route the heavy traffic over router F to router B? Should B,D be the correct answer?

Question:109
Refer to the exhibit. Currently the two eBGP links between AS100 and AS200 have an
average inbound load of 65% and 20% respectively. After further investigation, traffic to
10.10.1.16/28 accounts for 45%, and traffic to 10.10.1.32/28 and to 10.10.1.48/28 each
account for 20% of the inbound load. The BGP attributes are currently set at their default
values in both autonomous systems.
If you want to influence how AS200 sends traffic to AS100, which eBGP configurations would
you configure in AS100 to influence AS200 to use the eBGP links more evenly? (Choose two.)

A. neighbor 192.168.30.2 route-map as_50 out
B. neighbor 192.168.20.2 route-map as_50 out
C. route-map as_50 permit 10
match ip address 50
set metric 150
access-list 50 permit 10.10.1.16 0.0.0.240
D. route-map as_50 permit 10
match ip address 50
set metric 150
access-list 50 permit 10.10.1.32 0.0.0.240

please, anyone?

reddy,

B,C is the best answer, the reason being that with B,C, the whole traffic for 10.10.1.16 network is routed towards router A and the other two are filtered out, which makes total traffic towards this router through the first link as 45% (down from 65%)- Remember we are required to balance the traffic on the two LINKS and NOT the 3 routers.

Thanks Tai – but I’m not understanding how B,C re-directs 10.10.1.32 and .48 traffic to the other side. The lowest MED wins so RtrA having a higher MED than RtrB for the .16 traffic should force it to RtrB. The .32 and .48 are still tie.

My understanding is lower MED wins and if no match in RM then the traffic is routed as normal not blocked. Default MED is 100. Are my assumptions not correct?

reddy

Thanks for making me re-consider and now I am wondering if any of these combinations is correct- The reason is that the default MED is 0 (not 100)- Why is he giving 150, instead of say 1, or 10?? Is he confusing it with some other P/A ?? I have a feeling that this might be the case, I hope in exam we get the right choices.

In the current scenario, however, B,D does seem to be a better option, although still don’t know whether this was the intended route, and still no clear indication of the route choices of the other two routes.

Any exam takers’ comments if they saw this in the exam????

The real world examples I found always implement MED on both routers not just one

B,C is the most popular answer so it must have some merit

You r right, MED is normally implemented on 2 routers, making one lower than other- Normally it is not compared against default, since default is 0- If you put one MED value only, it is bound to make that route of lesser priority- That’s what make me think that the question is not so simple, or it is missing something.

I would like to go with the right answer rather than the popluar one, however there is no clear right answer as far as I can see.

I found my assumption pertaining to RM was wrong – there is an implicit ‘deny any’ at the end.
I couldn’t find it in the current cert book but found it in an old 640-503 cert book

Question 4

“Based on the show ip bgp summary output. which two statements are true?”

Answer: A F

A – The BGP session to the 10.1.1.1 neighbor is established

This can also be verified by looking at the BGP table version and main routing table version at the top of the output and the TblVer in the neighbor outputs at the bottom. If these numbers all match, the neighbors are fully converged.

herbert-4D483238@fireden.netahmad-4D483238@fireden.netFinaly i found what i wanted.

jerry———–!
I think the answer is right.
MED is used to influence the neighbor AS routers to choose the best path to get into your AS.
But here the answer says that what route will router A choose to reach the given network.
As the decision is for out going route and with reference to router A only weight-age is the best solution.

please check whether i am right or not ?

Hey guys! Don’t you think that both of these ACLs are exactly equal:
access-list 50 permit 10.10.1.16 0.0.0.240
access-list 50 permit 10.10.1.32 0.0.0.240

0.0.0.240 – Wildcard mask! Right?
so 0s => those digits must match
1s => those digits we don’t care about

10.10.1.16 = 00001010.00001010.00000001.00010000
10.10.1.32 = 00001010.00001010.00000001.00100000
0.0.0.240 = 00000000.00000000.00000000.11110000

which means that both ACLs will permit 10.10.1.16
10.10.1.32
10.10.1.48
10.10.1.64
10.10.1.80
10.10.1.96
and so on in increments of 16
and deny all others!!
Guess something’s wrong!

Hi, I had my exam yesterday and first question there was that with redisribution of trafic between AS according to metric. Right answers are:

B. neighbor 192.168.20.2 route-map as_50 out
D. route-map as_50 permit 10
match ip address 50
set metric 150
access-list 50 permit 10.10.1.32 0.0.0.240

I had 100% froom BGP.

@ Adam

thanks for that! I was looking to ask someone.

Moss

@Adam
are you sure ? anyone have more details about the correct answer ?choose B.C or B.D

The correct answer is B.D. My explination is : Traffic for the 10.10.1.32 compares the two med values on router E and F, it sees that the med associated with it for choosing the path through E->A is 150 which is higher than the path throuth F->B ( which is set at the default value of 0 ) thus choosing to exit through router F ( remember with med lower is better ). Traffic for 10.1.1.16 is untouched.

im on my ccnp route exam nxt month

need latest 642-902 dumps. please mail it to bigbiru@gmail.com

The computer at my test center crashed halfway through ROUTE exam. I was on question 28 when the test error occured. I have to reschedule now and start all over again.

Thanks for this inffo guys!!!! you all goos cool i bet Huh?????

The Answers given by Adam and Alex are correct only dump to give correct answer is Cisco TestKing 642-902 v2010-10-21 by irshad 484q i think.

Question 6 is a bit strange. The order of BGP path determination is:

Is next hop available?
Weight
Local Preference
Locally Injected or learned by BGP?
AS path

This means that the NEXT means of determining the best path after locally injected is AS path, but they didnt mention the local preference was the same. So this is the answer, but its out of order.

adam and alex are completely right about B & D being the correct answer.

which statement is true about iBGP routers

a: must be fully meshed
b: can be in different AS
c: must be directly connected
d: do not need to be directly connected

answer should be a not d?

rogerbee… i think it is D ….

@fschris… so much research 4 1 lousy question… but you’re right, it’s D. thnx
and of course thnx to tut.com and all contributors

@Sergey

The access lists in the question you referenced are for different subnets. Actually, the wildcard masks listed in the question are incorrect, as it’s an invalid wildcard mask. It should be:

access-list 50 permit 10.10.1.16 0.0.0.15
access-list 50 permit 10.10.1.32 0.0.0.15

not:

access-list 50 permit 10.10.1.16 0.0.0.240
access-list 50 permit 10.10.1.32 0.0.0.240

Regardless….

The first access-list is for the IP range of 10.10.1.16-10.10.1.31.
The second access-list is for the IP range of 10.10.1.32-10.10.1.47.

Hope that helps.

@adam and @alex

Thankx for that info….both of u….like to thank reddy and tai for that initial discussion also….So the correct answer are B & D….

Hi guys following up on the same question 85 AS 200 and AS 100. I created a lab for it and tried both the access list in answer C and D. When i checked the sh running-config, it should up as 10.10.1.0 0.0.0.240 for both access-lists.

So according to me, B is definitely the correct option. It doesn’t matter whether you select option C or D. both are correct. I confirmed this in my lab, all three prefixes 10.10.1.16, 10.10.1.32 and 10.10.1.48 have their metrics changed to 150. Would appreciate it if someone can try this in a lab and see if they meet with the same results, because as per my findings the metric is changed for all 3 prefixes and that doesn’t resolve anything as the link B-F will now be overloaded with all traffic moving over it.

Running out of hair to pull, would appreciate someone trying this in a lab.

Hello guys..

does anyone have ccnp route 642-902 cbt, pass4sure or any dumps. kindly send me links on shariq2009@live.com or u can send here as well.

Thanksss

Hello,

A. All six routes will be installed in the routing table.
B. Two routes will be installed in the routing table.
C. Four routes will be installed in the routing table.
D. All the routes were redistributed into BGP from an IGP.
E. All the routes were originated by BGP with the network command.

Answers: C and D

can anyone explain why D?

Origin

Well known, mandatory: The origin of the route tells us if the route is internal to the originating AS. The legal values are:

* i – Internal/IGP
* e – External/EGP
* ? – incomplete

Note that this attribute refers to the originating router which is the router that advertised the route into BGP, and not the router receiving the route. That is, most routes will be internal since they will have been advertised by the normal means of a network statement:

r2:
router bgp 3
network 10.2.2.0 mask 255.255.255.0

On r0, we see this network as:

r0#show ip bgp 10.2.2.0
BGP routing table entry for 10.2.2.0/24, version 3
Paths: (1 available, best #1, table Default-IP-Routing-Table)
Not advertised to any peer
3
192.168.3.6 from 10.50.0.2 (10.3.3.1)
Origin IGP, metric 0, localpref 100, valid, internal, best

If this is changed to

r2:
router bgp 3
redistribute connected

we see

r0#show ip bgp 10.2.2.0
BGP routing table entry for 10.2.2.0/24, version 12
Paths: (1 available, best #1, table Default-IP-Routing-Table)
Not advertised to any peer
3
192.168.3.6 from 10.50.0.2 (10.3.3.1)
Origin incomplete, metric 0, localpref 100, valid, internal, best

Since the route has been redistributed from another routing protocol (ie connected) before getting into BGP, the origin is considered incomplete.

Can anybody tell me fees structure for CCNP for 3 papers

Thanks

can someone help me with this question from gony dump: http://i56.tinypic.com/16iil9y.jpg

From what I can see is that changing the MED/Metric to 150 for network 10.10.1.16/28 and annouce it to AS 200 will make AS 200 choose the path through router B.

Now 20% of the traffic is going via router A and 65% via router B. How can this be the correct answer? Or do I miss something ?

I may be crazy but I think both route map statements are wrong

according to route map logic the route map filters routes as well as setting the metrics.

route-map as_50 permit 10
match ip address 50
set metric 150
access-list 50 permit 10.10.1.32 0.0.0.240

without another route map permit statement allowing all other routes this would filter all other routes and only allow 10.10.1.32 to be advertised to the neighbor and then set the metric to 150 which would cause the routers to still use path B because of the better(lower) MED attribute – all traffic would take route B.

route-map as_50 permit 10
match ip address 50
set metric 150
access-list 50 permit 10.10.1.16 0.0.0.240

This would filter all other routes and allow only 10.10.1.16 to be advertised to the neighbor and set the metric to 150 and again all traffic would take the other through B. In fact it doesnt matter which neighbor you advertise to, it will cause all traffic to route out one path.

The route maps would have to be fixed by adding an addition statement permitting all other routes but not setting a metric

route-map as_50 permit 20

I guess we are supposed to assume that the route maps have that extra statement. Thats BS i think these questions should be written with full proper configurations and not half configs with assumptions

hi….in BGP load sharing quest. within AS 100 and 200 to equalize load of 65% and 20%, given in dumps, what are the right answer, as it seems me wrong……

Hello Friends,

I just started to study the ROUTE test after taking almost two years off from passing the CCNA. I am planning to take the ROUTE test in two months. Are the Sims, Drag and Drop, Questions, and everything else on this site still valid for the ROUTE test?

Thank you all!

For the accompanying router output, which of the following statements describes the state that neighbor 172.16.254.3 is in?
Select the best response.

A. 
The router will not accept connections from the peer.
B. 
The router has sent out an active TCP connection request to the peer.
C. 
The router is listening on its server port for connection requests from the peer.
D. 
BGP can exchange routing information in this state.
Answer: C
Can someone explain the answer plz

I too have a problem with question 6,
BGP contains two paths to a destination. Assuming both routes were originated locally and have an equal weight. what will be the next determining factor in choosing the best path?

A – lowest MED
B – highest local preference
C – lowest neighbor IP address
D – lowest origin code
E – shortest AS-path

Answer: B

By saying what’s next after after local origion, they must imply that local preference has already been evaluated and skipped due to being default, so the next would be shortest-AS path.
