Scenario

In this activity, you will demonstrate and reinforce your ability to implement inter-VLAN routing, including configuring IP addresses, VLANs, trunking, and subinterfaces.

Instructions

Configure the devices to meet the following requirements.

  • Assign IP addressing to R1 and S1 based on the Addressing Table.
  • R1(config-if)#no shutdown
    R1(config-if)#interface GigabitEthernet0/1.10
    R1(config-subif)#encapsulation dot1Q 10
    R1(config-subif)#ip address 172.17.10.1 255.255.255.0
    R1(config-subif)#interface GigabitEthernet0/1.20
    R1(config-subif)#encapsulation dot1Q 20
    R1(config-subif)#ip address 172.17.20.1 255.255.255.0
    R1(config-subif)#interface GigabitEthernet0/1.30
    R1(config-subif)#encapsulation dot1Q 30
    R1(config-subif)#ip address 172.17.30.1 255.255.255.0
    R1(config-subif)#interface GigabitEthernet0/1.88
    R1(config-subif)#encapsulation dot1Q 88 native
    R1(config-subif)#ip address 172.17.88.1 255.255.255.0
    R1(config-subif)#interface GigabitEthernet0/1.99
    R1(config-subif)#encapsulation dot1Q 99
    R1(config-subif)#ip address 172.17.99.1 255.255.255.0
    R1(config-subif)#end
    S1(config)#interface vlan 99
    S1(config-if)#ip address 172.17.99.10 255.255.255.0
    S1(config-if)#no shut
  • Configure the default gateway on S1.
  • S1(config)#ip default-gateway 172.17.99.1
  • Create, name, and assign VLANs on S1 based on the VLAN and Port Assignments Table. Ports should be in access mode. Your VLAN names should match the names in the table exactly.
  • S1(config)#vlan 10
    S1(config-vlan)#name Faculty/Staff
    S1(config-vlan)#vlan 20
    S1(config-vlan)#name Students
    S1(config-vlan)#vlan 30
    S1(config-vlan)#name Guest(Default)
    S1(config-vlan)#vlan 88
    S1(config-vlan)#name Native
    S1(config-vlan)#vlan 99
    S1(config-vlan)#name Management
    S1(config-vlan)#
    S1(config-vlan)#interface range f0/11 - 17
    S1(config-if-range)#switchport mode access
    S1(config-if-range)#switchport access vlan 10
    S1(config-if-range)#interface range f0/18 - 24
    S1(config-if-range)#switchport mode access
    S1(config-if-range)#switchport access vlan 20
    S1(config-if-range)#interface range f0/6 - 10
    S1(config-if-range)#switchport mode access
    S1(config-if-range)#switchport access vlan 30
  • Configure G0/1 of S1 as a static trunk and assign the native VLAN.
  • S1(config)#interface g0/1
    S1(config-if)#switchport mode trunk
    S1(config-if)#switchport trunk native vlan 88
  • All ports that are not assigned to a VLAN should be disabled.
  • S1(config)#interface range f0/1-5,g0/2
    S1(config-if-range)#shutdown
  • Configure inter-VLAN routing on R1 based on the Addressing Table.
  • Verify connectivity. R1, S1, and all PCs should be able to ping each other and the server.

you missed configuring inter-vlan routing:
R1(config) # int g0/1
R1(config-if) # no shut
R1(config-if) # _
