  OSPF Multi-Area Configurationg We will use the following topology: Above we have R1 and R2 in area 0, the backbone area. Between R1 and R3, we will use area 1 and between R2/R4 we will use area 2. R3 and R4 have a loopback interface with an IP address that we will advertise in their area. Configuration Let’s start with all network commands to get OSPF up and running. The network command defines to which area each interface will belong.First, we will configure R1 and R2 for the backbone area: R1(config)# router ospf 1 R1(config-router)# network 192.168.12.0 0.0.0.255 area 0 R2(config)# router ospf 1 R2(config-router)# network 192.168.12.0 0.0.0.255 area 0 Let’s configure R1 and R3 for area 1: R1(config)# router ospf 1 R1(config-router)# network 192.168.13.0 0.0.0.255 area 1 R3(config)# router ospf 1 R3(config-router)# network 192.168.13.0 0.0.0.255 area 1 R3(config-router)# network 3.3.3.3 0.0.0.0 area 1 And last but not least, R2 and R4 for area 2: R2(config)# router ospf 1 R2(
