Goal: Build this setup in packet tracer and document it

Configure Multi-Layer Switches

1. Enable routing on each MLS

2. Create Vlans

• Only two vlans need to be configured on each MLS

vlan 100 name West_Clinic

vlan 110 name West_Admin

vlan 200 name Central_Clinic

vlan 210 name Central_Admin

vlan 300 name East_Clinic

vlan 310 name East_Admin

3. Configure VLAN Interfaces

• West MLS default gateways for its two vlans

• Central MLS default gateways for its two vlans

• East MLS default gateways for its two vlans

4. Configure Trunk Ports to Edge Switches

• On each MLS:

Configure Edge Switches

• Define the appropriate vlans

• Repeat for all switches

• Assign VLANs to Access Ports

example for North-West-Wing-SW access ports for vlan 100

example for North-West-Wing-SW access ports for vlan 110

• Assign the trunk port to the MLS

Configure PCs

• Their default gateways is the VLAN IP configured on the MLS switch

• An IP within the VLAN scope

• attached to an access port on the switch

Troubleshooting

• Hospital West devices can ping each other and are all setup, but the other two vlans can not

• Useful commands for me were:

show ip interface brief to check if VLAN interfaces were up

show interfaces trunk to check if trunk lines were carrying VLANs correctly

show vlan brief to check if PCs were assigned to correct VLANs

show running-config | include ip routing to check if routing was enabled. This was the key for me, because I saw that I did not have IP routing configured on 2 / 3 MLS switches
