     426== Distribution Layer ==
     427
     428For the lab purposes, we are using an L3 capable switch platform to illustrate a manageable L2 switch. We need to configure following on the '''FAC1-BLD1-FL2''',
     429
     430* Management Network
     431* Trunk Ports
     432*  Access Ports
     433
     434=== Configure Management Network ===
     435
     436* Create VLAN 2 which is the MGT Network for Faculty 1. Then assign an IP address for the VLAN 2 interface.

     451=== Configure Trunk Ports ===
     452
     453* Before configuring trunks we need to define the vlans first.

     460
     461* This FAC1-BLD1-FL2 has two trunk ports configure them to allow VLAN 10,20 to fa1/15 and VLAN 20 on fa1/14. We need to configure Native VLAN to VLAN 2 as well.

     495* Right-click on FAC1-BLD1-FL1 and select '''Configure'''
     496* Under Settings, Select
     497   * Port: 7
     498   * VLAN: 2

    471 ==== Connecting LAN to the Router ====
    472 
    473 Your Campus LAN is connecting to the outside through a border router. Your !CampusCore switch connects to this border router. In this link router's fast ethernet interface IP connects with the Core switch's vlan interface IP. Let's start configuring this link starting from the !CampusCore.
    474 
    475  - Login to !CampusCore switch and switch to config mode
    476  - Create VLAN 255 and name it Public

    482  - Then assign the IP Address to the VLAN interface. Get the IP from the [#point1 table]. In the real situation this VLAN could be a public IP range which is assign to your Institute. In this Lab we are using a private IP block.

    536 If You go to the Dept1PC and try a Ping to Dept2PC (10.0.20.1) and !BorderRt router LAN port(10.0.255.254), you will not get a reply. That is because you don't have inter VLAN routing yet. In this Lab we will enable OSPF in all the Layer 3 devices and we will add default routes as following table.
