Configuration Procedure

Step 1 Configure IP addresses for interconncetion interfaces and loopback interfaces.

[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ip add 10.0.123.1 24
[R1-GigabitEthernet0/0/0]int l0
[R1-LoopBack0]ip add 10.0.1.1 24

[R2]int g0/0/0
[R2-GigabitEthernet0/0/0]ip add 10.0.123.2 24
[R2-GigabitEthernet0/0/0]int l0
[R2-LoopBack0]ip add 10.0.2.2 24

[R3]int g0/0/0
[R3-GigabitEthernet0/0/0]ip add 10.0.123.3 24
[R3-GigabitEthernet0/0/0]int l0
[R3-LoopBack0]ip add 10.0.3.3 24

[R4]int g0/0/0
[R4-GigabitEthernet0/0/0]ip add 10.0.123.4 24
[R4-GigabitEthernet0/0/0]int g0/0/1
[R4-GigabitEthernet0/0/1]ip add 10.0.45.4 24
[R4-GigabitEthernet0/0/1]int l0
[R4-LoopBack0]ip add 10.0.4.4 24

[R5]int g0/0/0
[R5-GigabitEthernet0/0/0]ip add 10.0.45.5 24
[R5-GigabitEthernet0/0/0]int l0
[R5-LoopBack0]ip add 10.0.5.5 24

Step 2 Configure multi-area OSPF.

[R1]ospf 1 router-id 10.0.1.1
[R1-ospf-1]area 0
[R1-ospf-1-area-0.0.0.0]network 10.0.123.1 0.0.0.0
[R1-ospf-1-area-0.0.0.0]area 2
[R1-ospf-1-area-0.0.0.2]network 10.0.1.1 0.0.0.0

[R2]ospf 1 router-id 10.0.2.2
[R2-ospf-1]area 0
[R2-ospf-1-area-0.0.0.0]network 10.0.123.2 0.0.0.0
[R2-ospf-1-area-0.0.0.0]network 10.0.2.2 0.0.0.0

[R3]ospf 1 router-id 10.0.3.3
[R3-ospf-1]area 0
[R3-ospf-1-area-0.0.0.0]network 10.0.123.3 0.0.0.0
[R3-ospf-1-area-0.0.0.0]network 10.0.3.3 0.0.0.0

[R4]ospf 1 router-id 10.0.4.4
[R4-ospf-1]area 0
[R4-ospf-1-area-0.0.0.0]network 10.0.123.4 0.0.0.0
[R4-ospf-1-area-0.0.0.0]network 10.0.4.4 0.0.0.0
[R4-ospf-1-area-0.0.0.0]area 1
[R4-ospf-1-area-0.0.0.1]network 10.0.45.4 0.0.0.0

[R5]ospf 1 router-id 10.0.5.5
[R5-ospf-1]area 1
[R5-ospf-1-area-0.0.0.1]network 10.0.45.5 0.0.0.0

Step 3 Verify the OSPF configuration

<R4>display ospf peer
<R4>display ospf routing
<R4>display ospf lsdb

Step 4 Change the DR priorities of the device interfaces to affect DR election.

[R4-GigabitEthernet0/0/0]ospf dr-priority 255
[R3-GigabitEthernet0/0/0]ospf dr-priority 254
[R2-GigabitEthernet0/0/0]ospf dr-priority 0

<R1>reset ospf process
<R4>display ospf peer
<R4>display ospf peer verbose
<S1>reboot

Step 5 Import direct routes to OSPF.

<R1>display ospf routing
[R5-ospf-1]import-route direct
<R1>display ospf routing
<R1>display ospf lsdb ase
<R1>display ospf lsdb summary

Step 6 Observe the various types of LSAs.

display ospf lsdb router 10.0.1.1 display ospf lsdb network display ospf lsdb summary 10.0.45.0 display ospf lsdb asbr 10.0.5.5

Step 7 Observe the LSR,LSU, and LSAck packets.
