IP OSPF Database Sim

October 20th, 2010 in LabSim Go to comments

Command used to answer this question: show ip ospf database

By using this command you will get the Router ID

An example of the output of this command is shown below:

Router#show ip ospf database
OSPF Router with ID (192.168.2.2) (Process ID 1)

Router Link States (Area 0)

Link ID ADV Router Age Seq# Checksum Link count
192.168.1.1 192.168.1.1 141 0×80000002 0x00fca8 1
192.168.2.2 192.168.2.2 57 0×80000002 0x00fe9f 1
192.168.2.1 192.168.2.1 57 0×80000006 0x00a212 2


Net Link States (Area 0)

Link ID ADV Router Age Seq# Checksum
192.168.1.2 192.168.2.1 141 0×80000001 0×006218
192.168.2.2 192.168.2.2 57 0×80000001 0×006016

In this case the Router ID is 192.168.2.2

    I am going to CCIE written exam after few days.
    I am confused about Lab Sim questions.
    I think there is answer of some question in this page, But where is the question and how i can find that question.

    Plz help me

    passed today with 1000/1000

    There is some confusion on this sim and what it is. So I will tell you that it is a window with 4 squares on the left side. Click each one to see the question. Again, there are 4 questions and one topology. Click the ‘topology’ button at the bottom of the sim to see it. There is only one topology for all 4 questions. You do NOT log into any routers. All configuration is provided as text in the question.

    Topology – Note that the topology on the following line is simplified as there are other routers in the real topology but only the routers listed below are in use.

    R6(BGP AS40) —-> R3(BGP AS1000) —–> R2(BGP AS10)

    Question 1 BGP – Look at the configuration in R3. Of the following routes (30.30.0.0/16, 40.40.0.0/16, and 200.200.0.0/16) Which ones will show up in R2?

    Relavant R3 config is the following:
    router BGP 1000
    neighbor {R2 Loop IP address} remote-as 10
    neighbor {R2 Loop IP address} route-map BGP out
    neighbog {R2 Loop IP address} send community

    route-map 5 BGP permit
    match ip address 1
    set community no export
    route-map 10 BGP permit

    access-list 1 30.0.0.0 0.255.255.255

    Answer – 40.40.0.0/16 and 200.200.0.0/16 will show up. 30.30.0.0 will not be sent to R2 because it is now in the community of ‘no export’

    Question 2 QoS – Which statements are true about the following policy map:

    R1#show service-policy Gig1/0

    Class Somename1 Match-All
    ip dscp 40
    match packets size 200 min 1000 max
    NO match packets size min 500 max 500
    Set IP Prec 2

    Class Somename1 Match-All
    match packets size 500 min 500 max
    Set IP Prec 1

    Class default match any

    Answer…I forget the answers (there were 6 to choose from) but I believe I chose the ones that stated the following:
    1.) packets between 200 and 1000 bytes will be marked with prec 2
    2.) packets less that 488 will be marked with ip prec 2
    3.) I forget what I put for this one.

    Question 3 EIGRPv3 – Eigrp is not forming a neighbor relationship. Why?
    The question then shows only the runing config for 2 interfaces on each router.

    Answer – EIGRP needs to be enabled on BOTH routers. Do not select the option for EIGRP needs to be enabled on only one router because it is wrong.

    Question 4 BGP – R6 is redistributing the following routes (30.30.0.0/16, 40.40.0.0/16, and 200.200.0.0/16) into BGP. Which ones will show up in the routing table on R2.
    Now….this one was tricky for me as they provided no further configuration. So…I looked at the configuration for R3 in question 1 and deduced that R2 will only
    have subnets 40.40.0.0/16 and 200.200.0.0/16

    Enjoy

    I have some other results what Dburger is explaining for BGP….

    ok i did a lab of BGP what Dburger explained earlier, when “no-export” will be done on R3 , R2 will still see all 3 routes i.e 30.30.0.0/16 , 40.40.0.0/16 and 200.200.0.0/16 , but on R2 the no-export community will be tagged with 30.30.0.0 entry and it will not be advertised out of AS 10.

    eve,

    R6(BGP AS40) —->(no-export)—> R3(BGP AS1000) —–> R2(BGP AS10)

    I guess the no-export community value is set by R6 when it advertises the specified routes to R3, so that R3 won’t advertise those out to R2 via EBGP, but will advertise to other IBGP speakers within the same AS.

    Hope this helps, not just mug up the answers as such.Check the scenario and configs in real lab and work it out with your concepts.

    @pOp ..If R6 is setting “no-export” community then i agree it won’t go beyond R3.
    Thats why i always do labs wherever i can verify ..

    Hello,

    Is there any question (including lab or simlet also) apart from pass4sure v4.8?
    Can you describe them clearly, I have an exam tomorrow, any help will be appreciated.

    thanks a lot.

    Hello,

    First of all I want to thank you all. Finally, I completed the exam with 982/1000.
    I got one drag and drop, 1 simlet. Drag and drop was about policing, marking classification etc. like here but 3 of the explanations in the right side are different. For example not doing on the inbound interface, doing on the access layer switches, dropping excessive packets.

    Simlet was about frame relay, bgp, eigrp. There are four questions, my answers here:

    A1) eigrpv6 runs on routers
    A2) FF03:XX , FF04:XX are … group + 2..BE: RP + Sparse mode
    A3)499< pres 2, 200 presec 2, 200- 1500 apply class X
    A4)BGP conf problem + Eigrp metric + R3 no bgp relationship R5, R6

    Other questions were from Pass4sure Q195 v4.8

    Good luck you all.

    OSP Designated Router Router ID

    The question is about a show ip ospf database where there is an lsa type 2 in a broadcast network type ospf.

    The answer is: = 7.7.2.2 is the designated router router ID

    7.7.2.2 is the designated router router ID

    —————————————————————————–
    For Example :

    RouterA# show ip ospf database

    OSPF Router with id(192.168.239.66) (Process ID 300)

    172.16.65.6 172.16.65.6 1395 0×80001947 0xEEE1 4

    172.16.241.5 172.16.241.5 1161 0x8000007C 0x7C70 1

    172.16.27.6 172.16.27.6 1723 0×80000548 0×8641 4

    172.16.70.6 172.16.70.6 1485 0x80000B97 0xEB84 6

    Displaying Net Link States(Area 0.0.0.0)

    Link ID ADV Router Age Seq# Checksum

    172.16.1.3 192.168.239.66 1245 0x800000EC 0x82E

    Displaying Summary Net Link States(Area 0.0.0.0)

    172.16.244.0 172.16.241.5 1152 0×80000071 0x95CB

    This case 192.168.239.66 is the Designated Router RouterID (where there is an lsa type 2 in a broadcast network type ospf. )

    Exam Answer is = 7.7.2.2 is the designated router router ID

    Colby Reading is coming in all forms Cisco Press, whaptpieers, Cisco site and blogs. I am also using IPExperts BLS which includes videos and workbooks. I have been doing the workbooks using 3750 switches and GNS3. Starting in May I will also start using VRacks (I have 50 hours to use). I have completed CCNP, CCIP and CCDP as well as the CCIE R&S written.This will be my first attempt. I have read that only 3 percent of people that pass the CCNP attempt the LAB exam and of that only 10% pass their first attempt.
