Addressing Table

VLAN and Port Assignments Table


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

  • 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
  • All ports not assigned to a VLAN should be disabled.
  • Configure inter-VLAN routing on R1 based on the Addressing Table.
  • Verify connectivity. R1S1, and all PCs should be able to ping each other and the cisco.pka server.
