VTP Lab

Question:

The headquarter offices for a book retailer are enhancing their wiring closets with Layer3 switches. The new distribution-layer switch has been installed and a new access-layer switch cabled to it. Your task is to configure VTP to share VLAN information from the distribution-layer switch to the access-layer devices. Then, it is necessary to configure interVLAN routing on the distribution layer switch to route traffic between the different VLANs that are configured on the access-layer switches; however, it is not necessary for you to make the specific VLAN port assignments on the access-layer switches. Also, because VLAN database mode is being deprecated by Cisco, all VLAN and VTP configurations are to be completed in the global configuration mode. Please reference the following table for the VTP and VLAN information to be configured:

VTP_Lab.jpg

Requirements:

VTP Domain name cisco
VLAN Ids 20 21
IP Addresses 172.16.71.1/24 172.16.132.1/24

These are your specific tasks:

1. Configure the VTP information with the distribution layer switch as the VTP server
2. Configure the VTP information with the access layer switch as a VTP client
3. Configure VLANs on the distribution layer switch
4. Configure inter-VLAN routing on the distribution layer switch
5. Specific VLAN port assignments will be made as users are added to the access layer switches in the future.
6. All VLANs and VTP configurations are to completed in the global configuration. To configure the switch click on the host icon that is connected to the switch be way of a serial console cable.

Answer and Explanation:

1) Configure the VTP information with the distribution layer switch as the VTP server:


DLSwitch#configure terminal
DLSwitch(config)#vtp mode server
DLSwitch(config)#vtp domain cisco (use cisco, not CISCO because it is case sensitive)

(Requirement 2 will be solved later)
3) Configure VLANs on the distribution layer switch

To create VLANs on a switch, use the vlan vlanID# command:
DLSwitch(config)#vlan 20
DLSwitch(config)#vlan 21

Configure Ip addresses for Vlans:

DLSwitch(config)#interface vlan 20
DLSwitch(if-config)#ip address 172.16.71.1 255.255.255.0
DLSwitch(if-config)#no shutdown
DLSwitch(if-config)#interface vlan 21
DLSwitch(if-config)#ip address 172.16.132.1 255.255.255.0
DLSwitch(if-config)#no shutdown
DLSwitch(if-config)#exit

4) Configure inter-VLAN routing on the distribution layer switch

DLSwitch(config)#ip routing
DLSwitch(config)#exit
DLSwitch#copy running-config startup-config

2) Configure the VTP information with the access layer switch as a VTP client

ALSwitch#configure terminal
ALSwitch(config)#vtp mode client
ALSwitch(config)#vtp domain cisco
ALSwitch(config)#exit

ALSwitch#copy running-config startup-config

(Notice: Many reports said the copy running-config startup-config didn’t work but they still got the full mark)

    Hello! What about trunks ports Fa0/1? i think that you must configure its before sharing vlan informations.
    I will take 642-813 examen soon!

    Just follow what you need to do

  3. Shuyun
    August 31st, 2010

    It says to do all of the config in global config mode. Does this mean the VLANs don’t come preconfigured?

    By default Fa0/1 on both sides will be setup in DTP dynamic desirable mode and should create a trunk link with each other.

    Set it up, if the vlans pass from DSW to ASW then it works, if not config a trunk. Or if you want to be sure config the trunk anyway. Common sense, thats a CCNA kinda consideration

  5. Lulavinyl

    Is it not needed to use a routing protocol to get the Inter-VLAN routing? The only thing you can get by using the ip routing command is enabling the use of routing protocols, not the routing protocol indeed.

    Hi Guys, Please i need a good dump for the Switch Exam. I look forward to seating it by next week.

  7. Preparing for SWITCH
    October 7th, 2010

    Lula, directly connected networks do not need a routing protocol.
    Also it maynot be neccessaryto creat the SVI ( int vlans) you can check the running config to see what has been preconfigured.Remember ” all configs are in the GLOBAL CONFIG MODE.” So you may not even need to go into the interface mode.

    Hi Prep for SWITCH

    Question does say – Configure VLANs on the distribution layer switch.
    So I think it is a requirement to configure SVIs.

    Otherwise how will the DL switch know about the VLANs connected to AL Switch?

  9. Alpha
    October 7th, 2010

    And also Lula and Prep for SWITCH – questin also asks to enable Intervlan routing.

    So yes ip routing needs to be included.

  10. Alpha
    October 8th, 2010

    Can someone tell me if we need to configure fa0/1 ports on both switches to create a trunk?
    or is that not required?

  11. Alpha
    October 8th, 2010

    For VTP intervlan routing do we have configure the trunk between L3 switch and L2 switch?

    Or is that not required?

    Just create VTP domain and mode and SVIs and ip routing on L3?
    And VPT domain and mode on L2.

    Do we have to put ip routing on L2 as well or just on L3 switch?

    what about the trunk the port between L2 and L3? Do we have to create a trunk and specify encapsulation as welll?

  12. christok
    October 21st, 2010

    well i’ve just tried practicing dis sim, d L3 switch does not share vlan information with d L2 switch without a trunk configured on f0/1 link of both switches. In an exam situation, use d show run conf to verify d config on both switches, if cisco has configured d f0/1 links to negotiat trunk, then you may not needneed to configure trunk negotiation, if not then you must configure it simple.

    What about question N#5.
    Specific Vlan port assignment will be made as users are added to the access layer switches in the future

  16. Anonymous
    October 31st, 2010

    Keith

    It means ‘dont bother setting vlan assignments to ports on the ALS’

    after all, which ports are vlan20 and which are vlan21? the sim doesnt say, so you cant do it

  17. Ahmed Adel
    November 2nd, 2010

    Guys take care you should configure VTP domain and mode first , before creating VLANs

  18. soup
    November 4th, 2010

    @ Ahmed Adel u r correct

    show interface trunk will tell u interfaces that r trunked

    THIS IS HOW I WILL BE ABLE TO ANSWER THIS SIMULATION wimax450@gmail.com

    @Chitu
    Why are you setting the ALSwitch(config)#spanning-tree vlan 1,20-21 root primary
    on the access switch and distributions for that matter? Its like starting to set secret and line passswords…
    Dont do anything unless its a task. Setting trunks, Spanning-Tree are not objectives, so dont configure it unless its not working. VTP is not advetised with out a trunk, thats right, BUT there might be hidden configs you cant see, so do a sh vtp stat on both devices to see if the VLANs is advitise out ;)
    In the CCIE lab exam you’ll fail if you configure other things then told to. I know several that was like, “hey wait a minut, thats not what what i would do in real life”…. And thats how most people fail the CCIE ;)

    GL with your exam!!

    5. Specific VLAN port assignments will be made as users are added to the access layer switches in the future

    Can anyone explain this point?

    Thanks ¡¡¡

    Anyone have idea about a simulation question [not VTP,VTP2, MLS with EIGRP, LACP with STP, STP, AAAdot1X] in almost all the dumps (P4S, Testking, flipper) with very long IOS commands as step 1, 2, 3,,,,,,,,,,, Becoz it’s too many pages. Need lot of time to finish.. Will it come for exam? Plz anyone tel me…!

    you are doing more than the question is asking you to do.

  33. Pika
    February 24th, 2011

    @chitchu
    why are you configuring both switches as root for vlans 1, 20-21?!

    DLSwitch(config)#spanning-tree vlan 1,20-21 root primary

    ALSwitch(config)#spanning-tree vlan 1,20-21 root primary

  34. Switcho
    March 7th, 2011

    Yep, just to be safe hardcode int fa0/1 on both ends as a trunk.

    otherwise vtp wont work

    In the election process all switches exchange BPDU frames to determine which switch has the lowest Bridge id BID ..The switch with the lowest BID becomes the root bridge..Each BPDU contains a BID identifying the source switch..BID priority value MAC extended ID.The path costs are calculated by adding port cost values along a given path..STA chooses the path with the lowest path cost..After STA determines which paths are available it configures ports into distinct port roles.. .ELECTING THE ROOT BRIDGE .Every spanning tree instance has a root bridge..It serves as a refrence point for all calculations..All switches in the domain participate in the election..After a switch reboots it sends out BPDU every 2 secs..Initially each switch identifies itself as the root bridge..If the root ID from a received BPDU is lower than the BID on the receiving switch the receiver updates its root ID..The switch forwards new BPDU with the lower root ID..Eventually the switch with the lowest BID ends up being identified as the root bridge for the spanning tree instance..BEST PATHS TO ROOT BRIDGE .After electing the root the STA starts determining the best paths to root from all destinations.The path info is determined by adding up port costs from each destination to the root..Port costs are defined by speed..The values have already been changed to accommodate the newer 10GB Ethernet may change again in future..Port cost is configured .SW1 config-if spanning-tree cost .To verify port cost path cost .SW1 show spanning-tree detail.The cost Field total cost to root.BPDU FIELDS .The 1st 4 fields identify STP version type status..The next 4 fields identify the root cost to the root..The last 4 fields are timer fields that determine how often BPDU are sent how long the info is retained.. EXTENDED SYSTEM ID .Can be ommited in certain configurations..Early STP was not designed for vlans..This field contains the VLAN id..Reduces the of bits available for priority so the increments for the priority change from 1 to 4096..3.MAC ADDRESS .If switches have the same priority extSID the switch with the lowest MAC has the lowest BID..With default configs the MAC is then the deciding factor..This can lead to an unpredictable root bridge..Its recommended that the desired switch be given a lower priority..Also ensures that the addition of switches to your network does not trigger a new election..CONFIG VERIFY BID .There are 2 ways to change priority..SW1 config spanning-tree vlan vlan-id root primary .Sets priority to 24576 or the next 4096 increment below the lowest priority detected on network..For backup use .
