for R1, R2 and R3, we'll use the same setup as previous lab . there's new setting on R3 and new router, R4 check here R3 interface FastEthernet0/1  ip address 172.16.1.3 255.255.255.0  duplex auto  speed auto ! router ospf 1  log-adjacency-changes  network 3.3.3.3 0.0.0.0 area 0  network 172.16.1.0 0.0.0.255 area 17  network 192.168.3.0 0.0.0.255 area 0 R4 interface Loopback0  ip address 4.4.4.4 255.255.255.255 ! interface Loopback1  ip address 10.1.1.1 255.255.255.0 ! interface Loopback2  ip address 10.2.2.2 255.255.255.0 ! interface FastEthernet0/1  ip address 172.16.1.4 255.255.255.0  duplex auto  speed auto ! router ospf 1  router-id 4.4.4.4  log-adjacency-changes  network 4.4.4.4 0.0.0.0 area 17  network 10.1.1.0 0.0.0.255 area 10  network 10.2.2.0 0.0.0.255 area 10  network 172.16.1.0 0.0.0.255 area 17 *correction on IP address between R3 and R4, don't use the diagram IP but follow...

we'll configure OSPF Hub and Spokes network, on router R1 we'll use sub-interface to connect to R2 and R3. setup the network as below's configuration R1 interface Loopback0  ip address 1.1.1.1 255.255.255.255 ! interface FastEthernet0/0  no ip address  duplex auto  speed auto ! interface FastEthernet0/0.2  encapsulation dot1Q 2  ip address 192.168.2.1 255.255.255.0 ! interface FastEthernet0/0.3  bandwidth 100000  encapsulation dot1Q 3  ip address 192.168.3.1 255.255.255.0 router ospf 1  log-adjacency-changes  network 192.168.2.0 0.0.0.255 area 0  network 192.168.3.0 0.0.0.255 area 0 R2 interface Loopback0  ip address 2.2.2.2 255.255.255.255 ! interface FastEthernet0/0  ip address 192.168.2.2 255.255.255.0  duplex auto  speed auto router ospf 1  log-adjacency-changes  network 192.168.2.0 0.0.0.255 area 0 R3 interface Loopback0  ip address 3.3.3.3 255...

we gonna use previous network layout and setting click here to see previous setup add more loopback on R2 interface Loopback21  ip address 200.1.2.2 255.255.0.0 ! interface Loopback22  ip address 200.2.2.2 255.255.0.0 ! interface Loopback23  ip address 200.3.2.2 255.255.0.0 ! interface Loopback24  ip address 200.4.2.2 255.255.0.0 ! interface Loopback25  ip address 200.5.2.2 255.255.0.0 now we'll configure address summarization on R2 for this address we'll configure this on R2 interface f0/1 only R2(config)#int fa 0/1 R2(config-if)#ip summary-address eigrp 1 200.0.0.0 255.248.0.0 now show routing table from R1 and R2 R1>sh ip rou ..
