At any point the current VLAN table can be viewed in the cli using do show vlan

Hospital Router

  1. Enable Routing
ip routing
  1. Add VLANS to router
vlan <number>
name <vlan_name>
  1. Add IP Address to VLAN interfaces
interface vlan <vlan#>
ip address <ip_address> <subnet_mask>
  1. Configure Trunk Ports on Core Switches
interface range GigabitEthernet0/1-2
switchport mode trunk encapsulation dot1q
switchport mode trunk

North Core Switch

  1. Add VLANS to switch
  2. Configure Trunk port and Connect to Hostpital Router and connect via GigabitEthernet 
int range gigabitEthernet0/1-2
switchport mode trunk

North Edge Switch

Add VLANS to switch as shown above

  1. Assign 6 ports to Clinic (6 - 11 VLAN 200)
int range FastEthernet 0/6-11
switchport access vlan 200
