VLAN and Port Assignments Table

VLAN Name Interface
10 Faculty/Staff F0/11-17
20 Students F0/18-24
30 Guest(Default) F0/6-10
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.

Instructions

Configure the devices to meet the following requirements.

  • Assign IP addressing to R1 and S1 based on the Addressing Table.
  • Configure the default gateway on S1.
  • 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.
  • Configure G0/1 of S1 as a static trunk and assign the native VLAN.
  • All ports that are 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 server.
