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.

Interface g0/0 is never configured and interface g0/1 is only enabled in the answer script not the instruction
you missed configuring inter-vlan routing:
R1(config) # int g0/1
R1(config-if) # no shut
R1(config-if) # _
