Configuring Central MLS

Hostname: Central-MLS

Needs layer 3 - Cisco Commands

  1. Open CLI -> enable -> conf t
  2. ip routing

Define appropriate VLANs from CLI (For all switches)

Cisco Commands: from Switch(config)#vlan x Name <name>

West MLS

  • West Clinic
  • West Admin

Central MLS

  • All

East MLS

  • East Clinic
  • East Admin

Create VLAN interfaces to act as the default gateway for area VLANS

Cisco Commands:

  • from Switch(config)# interface vlan x
  • ip address x.x.x.x 255.x.x.x

INTERFACES

  • VLAN 100: ip address 192.168.10.1 255.255.255.0
  • VLAN 110: ip address 192.168.11.1 255.255.255.0
  • VLAN 200: ip address 192.168.20.1 255.255.255.0
  • VLAN 210: ip address 192.168.21.1 255.255.255.0
  • VLAN 300: ip address 192.168.30.1 255.255.255.0
  • VLAN 310: ip address 192.168.31.1 255.255.255.0

Configuring Trunk Ports to the Edge Switches

Encapsulation

  • Before setting switchport trunk mode we need to configure encapsulation on Central MLS.

Cisco Commands: switchport trunk encapsulation dot1q

Configuring trunk ports

Cisco Commands:

  • From switch(config)# interface FastEthernet0/x
  • config(if)# switchport mode trunk
  • config(if)# switchport trunk allowed vlan add <vlan #>

West MLS

  • FA0/1 Trunk to North-West-Wing Switch (vlan 100)
  • FA0/2 Trunk to South-West-Wing Switch (vlan 110)
  • Gig0/1 Trunk to Central MLS (all)

Central MLS

  • FA0/1 Trunk to North-Central-Wing Switch (vlan 200)
  • FA0/2 Trunk to South-Central-Wing Switch (vlan 210)
  • Gig0/1 Trunk to West MLS (all)
  • Gig0/2 Trunk to East MLS (all)

East MLS

  • FA0/1 Trunk to North-East-Wing Switch (vlan 300)
  • FA0/2 Trunk to South-East-Wing Switch (vlan 310)
  • Gig0/1 Trunk to Central MLS (all)

Save Configuration

To save the current configuration, the command is: copy running-configuration startup-configuration or copy run start

Show Configuration

show run

Configure edge switches

Define appropriate Vlans

  • Add vlans vlan x name <name>
  • Assign to interfaces
    • (config)interface range FastEthernet0/x-y
    • ```(config-if-range)switchport access vlan z``

Assign proper IPs to each PC


Deliverable: All my computers can ping all my other computers
