ICND2 – InterVLAN Routing

May 3rd, 2015 in ICND2 200-101 Go to comments

If you are not sure about InterVLAN routing, please read my InterVLAN Routing Tutorial (Premium Tutorial)

Question 1

Question 2

Explanation

The two answers B and E list all the commands needed to configure interVLAN routing. Please notice that Cisco switch 2950, 2960 only support dot1Q trunking so we don’t need to specify which trunking encapsulation to use in this case. For Cisco switches 3550 or above we have to use these commands instead:

Switch3550(config-if)#switchport trunk encapsulation dot1q
Switch3550(config-if)#switchport mode trunk

Question 3

Explanation

By default, all ports on a new switch belong to VLAN 1 (default & native VLAN). There are also some well-known VLANs (for example: VLAN 1002 for fddi-default; VLAN 1003 for token-ring…) configured by default -> A is not correct.

To communicate between two different VLANs we need to use a Layer 3 device like router or Layer 3 switch -> B is correct.

VLANs don’t affect the number of collision domains, they are the same -> C is not correct. Typically, VLANs increase the number of broadcast domains.
We must use a different network (or sub-network) for each VLAN. For example we can use 192.168.1.0/24 for VLAN 1, 192.168.2.0/24 for VLAN 2 -> D is correct.

A switch maintains a separate bridging table for each VLAN so that it can send frame to ports on the same VLAN only. For example, if a PC in VLAN 2 sends a frame then the switch look-ups its bridging table and only sends frame out of its ports which belong to VLAN 2 (it also sends this frame on trunk ports) -> E is correct.

We can use multiple switches to expand VLAN -> F is not correct.

    In Q2, don’t we need to specify the allowed VLANs to pass through fa0/1 ?

    Ali, as per my understanding, by default all VLANS are allowed to cross a trunk link. So, no need to specify which VLANs are allowed.

    So the “allowed vlan” means that only the specified vlans are trunked…

    Thanks Marc

    Question 1, answer B: “routed” should be “router1″

    @Ali
    By default, all vlans traffic is allowed on trunk link so we don’t have to specify the vlan. However if you want, you can block vlans on trunk link by configuration.

    Hope it helps.

    Could some1 send me the VCE Player also? My version isn’t working with the new VCE files and prompts me : “The file was created with a newer version of Visual CertExam that you have”

    1,4 were there

    Passed today 1000. Got different configuration of the Eigrp & frame Relay labs where there were different DLCIs and IP addresses, but same process was used to get answers (show commands, show ip protocols, show ip interface brief ).

    A question about GLBP and a question about netflow were on my test. You can find them here: http://www.examtut.com/2013/09/new-questions-in-ccna-200-120-hsrp-vrrp.html

    Study 9tut and this guy i found him really helpful. He has unique way of teaching http://www.danscourses.com If you can do all his videos again and again. Trust me you will get the concept. Also one thing i learned today is if you don’t know the concept it’ll be hard for you in the exam.

    All the best to every one in their path. Keep me in your good wishes.

    No explanations for Q4?

    Marco

    No further commands would be needed for the routing between the sub interfaces once they have been configured as the network would see them all as directly connected

    meaning they would automatically show in the routing table with a AD of 0

    I got Q3 and Q4 today in the ICND2 exam.
    Thanks 9tut.

    John,
    I just read your answer. Yeah, that’s what I thought. I had exactly this question (Q4) in my exam, this morning 😀
    Thank you.

    For anyone trying to re-create Q4 in GNS3 and using routers as hosts, dont forget to disable ip routing on the router/host and assign default gateway or you wont be able to route between vlans.

    Just took the test today – 980/1000 Questions 1 and 2 were from this page. Thanks 9tuts! Also got Frame Relay, EIGRP and OSPF labs- a lot of OSPF & quite a few EIGRP questions!

    THERE IS NO NEED FOR ANY DUMPS – just study one book (Wendel or Todd) and the you tube lessons available free for visual knowledge. Along with 9tuts these are enough for 900 and over marks with ease.

    But you MUST understand the concepts and not mug up the answer as they change the options and answers

    @all: We had to move all the questions and answers out of 9tut. We can only keep the explanation. You can download the questions and answers at: https://mega.co.nz/#!oIdESYbD!yyu33vygrfKPy4rcmcbV6qW2fxINNoTokuDM3CjA_og
