You have been tasked with configuring multilayer SwitchC, which has a partial configuration and has been attached to RouterC as shown in the topology diagram.

You need to configure SwitchC so that Hosts H1 and H2 can successful ping the server S1. Also SwitchC needs to be able to ping server S1. Due to administrative restrictions and requirements you should not add/delete VLANs, changes VLAN port assignments or create trunk links. Company policies forbid the use of static or default routing. All routes must be learned via EIGRP 650 routing protocol.

You do not have access to RouterC, RouterC is correctly configured. No trunking has been configured on RouterC.
Routed interfaces should use the lowest host on a subnet when possible. The following subnets are available to implement this solution:
Hosts H1 and H2 are configured with the correct IP address and default gateway.
SwitchC uses Cisco as the enable password.
Routing must only be enabled for the specific subnets shown in the diagram.


Answer and Explanation

In real life, there are two ways to configure interVLAN routing in this case:

+ Use RouterC as a “router on a stick” and SwitchC as a pure Layer2 switch. Trunking must be established between RouterC and SwitchC.
+ Only use SwitchC for interVLAN routing without using RouterC, SwitchC should be configured as a Layer 3 switch (which supports ip routing function as a router). No trunking requires.

The question clearly states “No trunking has been configured on RouterC” so RouterC does not contribute to interVLAN routing of hosts H1 & H2 -> SwitchC must be configured as a Layer 3 switch with SVIs for interVLAN routing.

We should check the default gateways on H1 & H2. Click on H1 and H2 and type the “ipconfig” command to get their default gateways.


We will get the default gateways as follows:

+ Default gateway:

+ Default gateway:

Now we have enough information to configure SwitchC (notice the EIGRP AS in this case is 650)

Note: VLAN2 and VLAN3 were created and gi0/10, gi0/11 interfaces were configured as access ports so we don’t need to configure them in this sim.

SwitchC# configure terminal
SwitchC(config)# int gi0/1
SwitchC(config-if)#no switchport -> without using this command, the simulator does not let you assign IP address on Gi0/1 interface.
SwitchC(config-if)# ip address ->RouterC has used IP so this is the lowest usable IP address.
SwitchC(config-if)# no shutdown
SwitchC(config-if)# exit
SwitchC(config)# int vlan 2
SwitchC(config-if)# ip address
SwitchC(config-if)# no shutdown
SwitchC(config-if)# int vlan 3
SwitchC(config-if)# ip address
SwitchC(config-if)# no shutdown
SwitchC(config)# ip routing (Notice: MLS will not work without this command)
SwitchC(config)# router eigrp 650
SwitchC(config-router)# network
SwitchC(config-router)# network
SwitchC(config-router)# network

NOTE : THE ROUTER IS CORRECTLY CONFIGURED, so you will not miss within it in the exam , also don’t modify/delete any port just do the above configuration. Also some reports said the “no auto-summary” command can’t be used in the simulator, in fact it is not necessary because the network is not used anywhere else in this topology.

After configure everything you should check the routing table of SwitchC (with the “show ip route” command”) to see if there are any EIGRP entries there. Also try pinging from Host1 & Host2 to the Server S1. If the pings are successful then your configuration is correct.

Also make sure you use the correct EIGRP AS number (in the configuration above it is 650 but it will change when you take the exam) but we are not allowed to access RouterC so the only way to find out the EIGRP AS is to look at the exhibit above. If you use wrong AS number, no neighbor relationship is formed between RouterC and SwitchC.

In fact, we are pretty sure instead of using two commands “network” and “network” we can use one simple command “network” because it is the nature of distance vector routing protocol like EIGRP: only major networks need to be advertised; even without “no auto-summary” command the network still works correctly. But in the exam the sim is just a flash based simulator so we should use two above commands, just for sure. But after finishing the configuration, we can use “show run” command to verify, only the summarized network is shown.

    i get the following massage, I dont understand wy i get the message,
    % overlaps with Vlan2 see below config. annybody know what i do wrong

    Sw_C(config-if)#ip address
    Sw_C(config-if)#no shut
    Sw_C(config-if)#int vlan 3
    %LINK-5-CHANGED: Interface Vlan3, changed state to up

    %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan3, changed state to up

    This is the right solution: see your mistake.

    Sw_C(config-if)#int vlan 2
    Sw_C(config-if)#ip add
    Sw_C(config-if)#no shut
    Sw_C(config-if)#int vlan 3
    Sw_C(config-if)#ip add
    Sw_C(config-if)#no shut

    Do you need to set the switch gi0/1 speed to 100 since the router has a fast Ethernet port?

    for me there is a mistake here
    they said : Due to administrative restrictions and requirements you should not add/delete VLANs, changes VLAN port assignments or create trunk links.

    as soon as you do a “no switchport” on Gi 0/1.
    this interface is no more assigned in a Vlan so you change the vlan assignment !?

    i think you should use 3 SVi and as the Gi 0/1 is in the native vlan, the rest of the lab works !

    -> You have routed interface (SVI)
    -> all vlan on interface are the same
    -> routing works for all as soon EIGRP is correct

    My config:

    In Cisco packet tracer – added Solution config:

    router eigrp 650
    no auto-summary

    Then I have to type “no auto-summary” also?

    Also in solution file:

    interface Vlan3
    ip address

    .252 ??

    June 27th, 2017

    Since gi 0/1 is natively in VL1, why isnt this answer to configure interface vlan 1 with This satisfies the requirement to not modify any VLAN port assignments. Or is it assumed that we should not modify any ports that have BEEN assigned previously by another admin?

    I guess you had AAAdot1x Lab Sim, don´t you?? did you configure a named ACLs or configure number ACL?

    what we should configure in the AAAdot1x ?named acl or number acl

    does the the question on the exam says what type of ACL we should use?

  29. Tobby
    July 29th, 2017

    @sss and @kopi
    better check this link http://www.certprepare.com/aaadot1x-lab-sim/comment-page-39#comment-222793 and the sim states that “not to use named ACLs” THEN I THINK you should configure number ACL instead:
    DSW1(config)#access-list 10 permit

    Anyways, that´s why I asked to @Aes to confirm

  30. kopi
    July 29th, 2017

    i know whats the difference between both types of ACL, my question was if the specification says which one should be used

  31. Tobby
    July 30th, 2017

    the sim states that “not to use named ACLs”

    I agree with El Diablo
    I would check vlan assignment of port gi 0/1
    I would not change any setting on port
    and create SVI for that vlan with IP

    and then normal EIGRP setting and it should work as well.

    Looks like 401q is no longer valid. Passleader 418q just released from today if anyone can provide us a full copy of the pdf.
