VLAN and Port Assignments Table
| VLAN | Name | Interface |
| 10 | Faculty/Staff | Fa0/11-17 |
| 20 | Students | Fa0/18-24 |
| 30 | Guest(Default) | Fa0/6-10 |
| 88 | Native | G0/1 |
| 99 | Management | VLAN 99 |
Scenario
In this activity, you will demonstrate and reinforce your ability to implement inter-VLAN routing, including configuring IP addresses, VLANs, trunking and subinterfaces.
Requirements
- Assign IP addressing to R1 and S1 based on the Addressing Table.
- Create, name and assign VLANs on S1 based on the VLAN and Port Assignments Table. Ports should be in access mode.
- Configure S1 to trunk, allow only the VLANs in the VLAN and Port Assignments Table.
- Configure the default gateway on S1.
- All ports not assigned to a VLAN should be disabled.
- 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 cisco.pka server.
