Introduction 

In this assessment you are configuring a network that is using EtherChannel and routing between VLANs. For the sake of time, you will not be asked to perform all configurations on all network devices as you may be required to do in a real network or other assessment. Instead, you will use the skills and knowledge that you have learned in the labs in this course to configure the router and switches in the topology. In addition to EtherChannel and inter-VLAN routing, this task involves creating VLANs and trunks, and performing basic router and switch configuration. 

You are required to configure host default gateways; however host addresses are preconfigured. 

You will practice and be assessed on the following skills: 

  • Configuration of initial settings on a router. 
  • Configuration of initial settings on a switch, including SVI and SSH. 
  • Configuration of VLANs.  
  • Configuration of switchport VLAN membership. 
  • EtherChannel configuration.  
  • Troubleshooting VLANs.  
  • Configuration of static trunking and DTP.  
  • Configuration of routing between VLANs on a Layer 3 switch.  
  • Configuration of router-on-a-stick inter- VLAN routing on a router.  
  • Configure default gateways on hosts.

Background / Scenario

A corporation is planning to implement EtherChannel and a new VLAN design in order to make the network more efficient. You have been asked to work on a design and prototype of the new network. You have created the logical topology and now need to configure the devices in order to evaluate the design. You will configure VLANs and access port VLAN membership on access layer switches. You will also configure EtherChannel and trunking. Finally, you will configure a router and a Layer 3 switch to route between VLANs. Some addressing had already been configured.

Step 2: Configure Trunking on the EtherChannels 

  1. Configure the port channel interfaces as static trunks. Disable DTP negotiation on all trunks. 
  2. Troubleshoot any issues that prevent the formation of the EtherChannels. 

Note: Packet Tracer requires configuration of trunking and DTP mode on both portchannel interfaces and the component physical interfaces. 

    • Konfigurera Port-Channel 1 som trunk
    • L3-SW1(config)# interface port-channel 1
    • L3-SW1(config-if)# switchport mode trunk
    • L3-SW1(config-if)# switchport trunk allowed vlan 10,20,30
    • L3-SW1(config-if)# exit
    • Konfigurera Port-Channel 2 som trunk
    • L3-SW1(config)# interface port-channel 2
    • L3-SW1(config-if)# switchport mode trunk
    • L3-SW1(config-if)# switchport trunk allowed vlan 10,20,30
    • L3-SW1(config-if)# end
    • L3-SW1# write memory
    • Sw-A: Konfigurera Port-Channel 1 som trunk
    • Sw-A(config)# interface port-channel 1
    • Sw-A(config-if)# switchport mode trunk
    • Sw-A(config-if)# switchport nonegotiate
    • Sw-A(config-if)# exit
    • Sw-A: Konfigurera Port-Channel 3 som trunk
    • Sw-A(config)# interface port-channel 3
    • Sw-A(config-if)# switchport mode trunk
    • Sw-A(config-if)# switchport nonegotiate
    • Sw-A(config-if)# end
    • Sw-A# write memory
    • Sw-B: Konfigurera Port-Channel 2 som trunk
    • Sw-B(config)# interface port-channel 2
    • Sw-B(config-if)# switchport mode trunk
    • Sw-B(config-if)# switchport nonegotiate
    • Sw-B(config-if)# exit
    • Sw-B: Konfigurera Port-Channel 3 som trunk
    • Sw-B(config)# interface port-channel 3
    • Sw-B(config-if)# switchport mode trunk
    • Sw-B(config-if)# switchport nonegotiate
    • Sw-B(config-if)# end
    • Sw-B# write memory

Step 3: Configure a static trunk uplink 

  1. On the Sw-C switch, configure the port that is connected to Edge-Router as a static trunk. 
  2. Configure the Management VLAN as the native VLAN. 
  3. Disable DTP on the port. 
    • Sw-C(config)# interface g0/1
    • Sw-C(config-if)# switchport mode trunk
    • Sw-C(config-if)# switchport trunk native vlan 99
    • Sw-C(config-if)# switchport trunk allowed vlan 40,50,60,99
    • Sw-C(config-if)# switchport nonegotiate
    • Sw-C(config-if)# end
    • Sw-C# write memory

Step 1: Configure inter-VLAN routing on the Layer 3 switch. 

  1. Configure Inter-VLAN routing on the L3-SW1 Layer 3 switch for all VLANs in the VLAN Table that are configured on L3-SW1. 
  2. Configure the switchport on L3-SW1 that is connected to Edge-Router with an IP address as shown in the Addressing Table. 
    • Aktivera Inter-VLAN routing på L3-SW1
    • L3-SW1(config)# ip routing
    • Konfigurera IP-adressering på interfacet anslutet till Edge-Router
    • L3-SW1(config)# interface g1/1/1
    • L3-SW1(config-if)# no switchport
    • L3-SW1(config-if)# ip address 10.0.0.2 255.255.255.0
    • L3-SW1(config-if)# no shutdown
    • L3-SW1(config-if)# end
    • L3-SW1# write memory

Step 2: Configure router-on-a-stick inter-VLAN routing on a router. 

  1. Configure inter-VLAN routing on Edge-Router for all the VLANs that are configured on the Sw-C switch. Use the information in the Addressing Table. 
  2. Be sure to configure descriptions of all interfaces. 
    • Förberedelse av interface G0/0/1
    • Edge-Router(config)# interface g0/0/1
    • Edge-Router(config-if)# no ip address
    • Edge-Router(config-if)# shutdown
    • Edge-Router(config-if)# exit
    • Konfiguration av Sub-interface för VLAN 40
    • Edge-Router(config)# interface g0/0/1.40
    • Edge-Router(config-if)# description Gateway to VLAN 40
    • Edge-Router(config-if)# encapsulation dot1q 40
    • Edge-Router(config-if)# ip address 10.0.40.1 255.255.255.0
    • Edge-Router(config-if)# no shutdown
    • Edge-Router(config-if)# exit
    • Konfiguration av Sub-interface för VLAN 50
    • Edge-Router(config)# interface g0/0/1.50
    • Edge-Router(config-if)# description Gateway to VLAN 50
    • Edge-Router(config-if)# encapsulation dot1q 50
    • Edge-Router(config-if)# ip address 10.0.50.1 255.255.255.0
    • Edge-Router(config-if)# no shutdown
    • Edge-Router(config-if)# exit
    • Konfiguration av Sub-interface för VLAN 60
    • Edge-Router(config)# interface g0/0/1.60
    • Edge-Router(config-if)# description Gateway to VLAN 60
    • Edge-Router(config-if)# encapsulation dot1q 60
    • Edge-Router(config-if)# ip address 10.0.60.1 255.255.255.0
    • Edge-Router(config-if)# no shutdown
    • Edge-Router(config-if)# exit
    • Konfiguration av Sub-interface för VLAN 99
    • Edge-Router(config)# interface g0/0/1.99
    • Edge-Router(config-if)# description Gateway to VLAN 99
    • Edge-Router(config-if)# encapsulation dot1q 99
    • Edge-Router(config-if)# ip address 10.0.99.17 255.255.255.240
    • Edge-Router(config-if)# no shutdown
    • Edge-Router(config-if)# exit
    • Återaktivering av det fysiska interfacet G0/0/1
    • Edge-Router(config)# interface g0/0/1
    • Edge-Router(config-if)# no shutdown
    • Edge-Router(config-if)# end
    • Edge-Router# write memory

Step 3: Configure default gateways on hosts. 

  1. Configure default gateway addresses on all hosts on the LANs. 
  2. Verify connectivity between all hosts on both LANs with each other and the Outside Server server.
  3. Verify that a host can connect to the SVI of switch Sw-C over SSH.
