Cisco: OSPF multi-area network

Setup IP address

R1:

/ip address add address=10.0.1.1/30 interface=ether1
/ip address add address=10.1.1.1/30 interface=ether2

R2:

/ip address add address=10.0.1.2/30 interface=ether1
/ip address add address=10.1.2.1/30 interface=ether2
/ip dhcp-client add interface=ether3 disabled=no        # kalau ether3 DHCP client
/ip firewall nat add chain=srcnat out-interface=ether3 action=masquareade
/ip firewall nat print

R3:

/ip address add address=10.1.1.2/30 interface=ether1
/ip address add address=192.168.1.1/24 interface=ether2

R4:

/ip address add address=10.1.2.2/30 interface=ether1
/ip address add address=192.168.2.1/24 interface=ether2

Setup OSPF

R1:

/routing ospf instance enable default
/routing ospf area add name=area1 area-id=0.0.0.1
/routing ospf network add network=10.0.1.0/24 area=backbone
/routing ospf network add network=10.1.1.0/30 area=area1

R2:

/routing ospf instance enable default
/routing ospf area add name=area2 area-id=0.0.0.2
/routing ospf network add network=10.0.1.0/24 area=backbone
/routing ospf network add network=10.1.2.0/30 area=area2

R3 configuration:

/routing ospf instance enable default
/routing ospf area add name=area1 area-id=0.0.0.1
/routing ospf network add network=10.1.1.0/30 area=area1

R4 configuration:

/routing ospf instance enable default
/routing ospf area add name=area2 area-id=0.0.0.2
/routing ospf network add network=10.1.2.0/30 area=area2

Cek route

R3:

/routing ospf interface print
/routing ospf neighbor print
/ip route print 
    

Redistribute Connected

/routing ospf instance set 0 redistribute-connected=as-type-1 
/routing ospf instance print 

Cek

/routing ospf interface print
