We continue the networking build and design with multi-area OSPF.  Build the following network. (multi-area OSPF, VLANs)
Configure OSPF in each router with router ID and loopback addressing.
Topology:
5 Routers with serial ports
(Right Leg – router 0 connects to R1; R1 Connects to R2)
(Left Leg – Router 0 connect to R3.  R3 connects to R4)
2 Switches (switch is attached to last router on each leg network)  1 switch connects to R2 and 1 switch connects to R4.
1 end device attached to each switch
Subnet the addresses for the device requirement
Configure sub interfaces on router connected to switches.
Routers at the top of the network are Area 0  (outbound interface from router 0 to inbound interface of router 1 is area 0)
(outbound interface from router 0 to inbound interface of router 3 is area 0)
Outbound of router 1 interface and router 2 are Area 1)
Outbound of router 3 interface and router 4 are Area 2)
Network Left Leg:  Area 1
192.168.100.0/24; network host requirement is 100 devices
VLAN 100
Network Right Leg: Area 2
172.16.20.0/22; network host requirement is 50 devices
VLAN 200
Configure mulit area OSPF and ping successfully from Leg A to Leg B.
