EIGRP Stub Sim

Question

TUT Corporation has just extended their business. R3 is the new router from which they can reach all Corporate subnets. In order to raise network stableness and lower the memory usage and broadband utilization to R3, TUT Corporation makes use of route summarization together with the EIGRP Stub Routing feature. Another network engineer is responsible for this solution. However, in the process of configuring EIGRP stub routing connectivity with the remote network devices off of R3 has been missing.

EIGRPStubSim

Presently TUT has configured EIGRP on all routers in the network R2, R3, and R4. Your duty is to find and solve the connectivity failure problem with the remote office router R3. You should then configure route summarization only to the distant office router R3 to complete the task after the problem has been solved.

The success of pings from R4 to the R3 LAN interface proves that the fault has been corrected and the R3 IP routing table only contains two 10.0.0.0 subnets.

Answer and Explanation:

First we have to figure out why R3 and R4 can not communicate with each other. Use the show running-config command on router R3

EIGRPStubSim_show_running_config_R3

Notice that R3 is configured as a stub receive-only router. The receive-only keyword will restrict the router from sharing any of its routes with any other router in that EIGRP autonomous system. This keyword will also prevent any type of route from being sent.

Therefore we will remove this command and replace it with the eigrp stub command:

R3#configure terminal
R3(config)#router eigrp 123
R3(config-router)#no eigrp stub receive-only
R3(config-router)#eigrp stub
R3(config-router)#end

Now R3 will send updates containing its connected and summary routes to other routers. Notice that the eigrp stub command equals to the eigrp stub connected summary because the connected and summary options are enabled by default.

Next we will configure router R3 so that it has only 2 subnets of 10.0.0.0 network. Use the show ip route command on R3 to view its routing table

R3#show ip route

EIGRPStubSim_show_ip_route_R3_no-summary.jpg

 

Because we want the routing table of R3 only have 2 subnets so we have to summary sub-networks at the interface which is connected with R3, the s0/0 interface of R4.

There is one interesting thing about the output of the show ip route shown above: the 10.2.3.0/24, which is a directly connected network of R3. We can’t get rid of it in the routing table no matter what technique we use to summary the networks. Therefore, to make the routing table of R3 has only 2 subnets we have to summary other subnets into one subnet.

In the output if we don’t see the summary line (like 10.0.0.0/8 is a summary…) then we should use the command ip summary-address eigrp 123 10.2.0.0 255.255.0.0 so that all the ping can work well.

In conclusion, we will use the ip summary-address eigrp 123 10.2.0.0 255.255.0.0 at the interface s0/0 of R4 to summary.

R4>enable
R4#configure terminal
R4(config)#interface s0/0
R4(config-if)#ip summary-address eigrp 123 10.2.0.0 255.255.0.0

Now we jump back to R3 and use the show ip route command to verify the effect, the output is shown below:

EIGRPStubSim_show_ip_route_R3_final_no_summary.jpg

(But please notice that the ip addresses and the subnet masks in your real exam might be different so you might use different ones to solve this question)

But in your real exam, if you see the line “10.0.0.0/8 is a summary,….Null0” then you need to summary using the network 10.0.0.0/8 with the command “ip summary-address eigrp 123 10.0.0.0 255.0.0.0” . This configuration is less optimize than the first but it summaries into 2 subnets as the question requires (maybe you will not see this case, don’t worry!).

The command “copy running-config startup-config” will not work so try using this command; just skip if it doesn’t work.

    I have some doubt,it will make problem if 15.x IOS routers are in use (they inject /32 routes for interfaces with L label).
    Another problem ,if auto-summary is in effect in R3 (that will inject Null0 for 10.0.0.0/8),R3 will not install summary route of 10.0.0.0/8 from R4 via EIGRP.Because Sumamry Route with Null0 has composite metric lower than Summary Route learned from R4.As a result,R3 can not connect to network 10.2.3.0/24 and Loopbacks of R2.
    //*********//
    Everything with lab will be true,if 12.x IOSs are in use and auto-summary is disabled in R3.
    So,it will accept and add R4’s summary route.Hence,only 2networks (one with D ,another with C labeled) present in routing table of R3.

    Hi guys, I have passed my ccnp routing exam yesterday at (23/1/2017) with score (973), actually the dumps of 149q and 41q tagwa is still valid.
    Most the question came from the 41q tagwa, so you have to study it very well,
    BUT it important to study also the dump of 183q/32q/8q because it contain a lot of questions that you will not find them in both 149q and tagwa 41q dumps, in my exam none of new questions of 183q/32q/8q came, but I recommended to studied any way
    The sim in my exam:
    -ospf eigrp redistribution
    -ospf evaluation
    -ospfv3 with virtual-link
    -ospf sim
    -policy based routing sim
    The drag and drop:
    -CHAP drag (in tagwa 41q)

    Important notes about the sims:
    Regarding to sims , you should be careful because you might find that there some minor changes in the sims (like ip addess, subnets , ospf process numbers , eigrp autonomous number and so on) so check with show run command if that possible before starting the configuration, don’t not rush to configure blindly .
    In my exam, there was some little change in ospf evaluation, I mentioning below the question with changed answer:
    The question:
    Which of the following statements is true about the serial links that terminate in R3?
    A. The R1-R3 link needs the neighbor command for the adjacency to stay up
    B. The R2-R3 link OSPF timer values are 30, 120, 120
    C. The R1-R3 link OSPF timer values should be 10,40,40
    D. R3 is responsible for flooding LSUs to all the routers on the network.
    In dumps sim you will find that the correct answer is B, but in my exam that was not true, because I found that the exam changed the link R2-R3 timers to 10,40,40 and it was point-to-point link.
    also I found The link R1-R3 timer was 30,120,120 non-broad cast link, so both of the answers A , B are wrong .
    Also D was wrong because, R3 was not the DR in all the links,
    The right answer was A, because the link R1-R3 is non-broad-cast link so neighborship should be configured manually.
    So it is important to be carful .

    Important notes about tagwa 41q dump:
    It is important to mention that in tagwa 41q dump there some questions with wrong answers, here below I mentioned the question with the wrong answers:
    Question 2
    Refer to the following configuration command.
    router(config)# ip nat inside source static tcp 172.16.10.8 8080 172.16.10.8 80
    Which statement about the command is true?
    A. Any packet that is received in the inside interface with a source IP port address of
    172.16.10.8:80 is translated to 172.16.10.8:8080.
    B. Any packet that is received in the inside interface with a source IP port address of
    172.16.10.8:8080 is translated to 172.16.10.8:80.
    C. The router accepts only a TCP connection from port 8080 and port 80 on IP address
    172.16.10.8.
    D. Any packet that is received in the inside interface with a source IP address of 172.16.10.8
    is redirected to port 8080 or port 80.
    Answer:A
    Tagawa say the right answer is A , but that wrong the right answer is B (this question came in my exam)

    Question 28
    A network engineer wants to ensure an optimal end-to-end delay bandwidth product. The delay is
    less than 64 KB. Which TCP feature ensures steady state throughput?
    A. Window scaling
    B. Network buffers
    C. Round-trip timers
    D. TCP acknowledgments
    Answer:A
    Also that wrong the right answer is B

    I don’t understand the mask used for summarization. As many have said, I think it should be 255.255.240.0 If you breakdown the third octet in the networks you see in R3’s route table, you have:

    2-0000 0010
    3-0000 0011
    4-0000 0100
    5-0000 0101
    6-0000 0110
    7-0000 0111
    8-0000 1000
    9-0000 1001

    So, the first three bits of that 3rd octet are what’s in common. That gives you a /20 and .240 for those four bits. Can anyone explain why this answer says it’s 255.255.0.0 and not 255.255.240.0???

    Even this online calculator confirms this:

    https://nubem.com/ip-summarization-tool/

    The summary is 10.2.0.0 /20

  10. Anonymous
    February 8th, 2017

    Just proved what many have been saying. I had misconfigure the summary address with a mask of 255.255.255.240. It should be 255.255.240.0 Here’s my config under R4 s1/0 (for the summary address):

    interface Serial1/0
    ip summary-address eigrp 123 10.2.0.0 255.255.240.0 5

    Now I see just two entries for the 10.x.x.x network:

    R3#sh ip route | b Gate
    Gateway of last resort is not set

    172.16.0.0/24 is subnetted, 1 subnets
    C 172.16.1.0 is directly connected, FastEthernet0/0
    10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
    D 10.2.0.0/20 [90/2195456] via 10.2.3.4, 00:02:15, Serial1/0
    C 10.2.3.0/24 is directly connected, Serial1/0
    R3#

    Bam! mic drop :)

    Yes, the proper summarization of the range 10.2.2.0 – 10.2.9.0 is 10.2.0.0 /20

    Therefore, the command “ip summary-address eigrp 123 10.2.0.0 255.255.0.0” is wrong.
    It should be “ip summary-address eigrp 123 10.2.0.0 255.255.240.0”.

    However, the exam simulator probably checks *how many* 10.x.x.x entries are in the routing table and since the two commands have the same effect in that regard you’ll probably won’t lose points by using a /16 mask. Regardless, I’d use /20 just to play safe.

    The Right answer is :
    ip summary-address eigrp 123 10.2.0.0 255.255.240.0

    just try to disable the auto summary on R4
    and configure the ip summary with /16

    the output on R3 will be 3 subnets with /16 and 2 subnets with /20:

    The reason we dont configure this on R2 is then we would still have the route for the R4 to R2 ethernet connection in the routing table of R3 making 3 10. routes in the table. Here is my output from R3 after configuring the summary on R2 instead of R4:

    /20 is more correct but if you have 2 subnets with /16 is valid.

    Hello

    The bit I struggle to understand is “10.0.0.0/8 is a summary,….Null0” if the route in routing tabel is already summarized as “10.0.0.0/8 is a summary,….Null0” and Null0 is garbage can- so how can we still summarize by using

    to summary using the network 10.0.0.0/8 with the command “ip summary-address eigrp 123 10.0.0.0 255.0.0.0” .

    ip summary-address eigrp 123 10.2.0.0 255.255.240.0 (/20) is more optimal summary address.
