[R5-ospf-1-area-0.0.0.1]network 10.0.45.5 0.0.0.0

Step 3 Verify the OSPF configuration.

<R3>reset ospf process
<R2>display ospf peer
<R5>display ospf routing
<R2>display ospf lsdb

Step 4 Configure route summarization for OSPF inter-area routes and AS external routes

[R2]display ospf routing
<R4>display ospf routing

[R4-ospf-1-area-0.0.0.1]abr-summary 10.5.0.0 255.255.254.0
[R2-ospf-1-area-0.0.0.2]abr-summary 10.3.0.0 255.255.254.0

[R2-ospf-1]import-route direct
[R2-ospf-1]asbr-summary 10.2.0.0 255.255.254.0

Step 5 Change the bandwidth reference value of OSPF.

[R1-ospf-1]bandwidth-reference 10000
[R2-ospf-1]bandwidth-reference 10000
[R3-ospf-1]bandwidth-reference 10000
[R4-ospf-1]bandwidth-reference 10000
[R5-ospf-1]bandwidth-reference 10000

[R4]display ospf routing

Step 6 Configure OSPF to import a defualt route.

[R1]ip route-static 0.0.0.0 0.0.0.0 10.0.1.1
[R1-ospf-1]default-route-advertise
[R1-ospf-1]default-route-advertise always
[R1-ospf-1]default-route-advertise always type 1

Step 7 Change the preferences of the two types of OSPF routes. 

<R3>display ip routing-table protocol ospf

[R1-ospf-1]preference 20
[R1-ospf-1]preference ase 50
[R3-ospf-1]preference 20
[R3-ospf-1]preference ase 50

Configuration Procedure

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

[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

[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.

### Step 1 Configure IP addresses for interconnection interfaces and loopback interfaces.

[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ip add 10.0.13.1 24
[R1-GigabitEthernet0/0/0]int l0
[R1-LoopBack0]ip add 10.0.1.1 24

[R3-GigabitEthernet0/0/1]int g0/0/2
[R3-GigabitEthernet0/0/2]ip add 10.0.23.3 24
[R3-GigabitEthernet0/0/2]int l0
[R3-LoopBack0]ip add 10.0.3.3 24

[R4]int g0/0/0
[R4-GigabitEthernet0/0/0]ip add 10.0.34.4 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

<R3>ping 10.0.13.1
<R3>ping 10.0.23.2
<R3>ping 10.0.34.4
<R5>ping 10.0.45.4

Step 2 Configure multi-area OSPF

[R1]ospf 1 router-id 10.0.1.1
[R1-ospf-1]area 2
[R1-ospf-1-area-0.0.0.2]network 10.0.1.1 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 multi-area OSPF configuration.

<R3>display ospf peer
[R5]dis ospf peer
<R3>display ospf routing

Step 4 Import AS external routes into the OSPF routing tables.

[R5-ospf-1]import-route direct

[R2]ip route-static 0.0.0.0 0.0.0.0 10.0.2.2
[R2]undo ip route-static 0.0.0.0 0.0.0.0 10.0.2.2

​ display ospf routing 0.0.0.0 0 display ospf routing 10.0.5.5 24

<R3>ping 10.0.5.5
<R3>ping 10.0.2.2

​ ### Step 5 Configure area 2 as a stub area display ospf routing

[R1-ospf-1-area-0.0.0.2]stub
[R3-ospf-1-area-0.0.0.2]stub

<R1>display ospf routing
<R1>display ospf lsdb

[R3-ospf-1-area-0.0.0.2]stub no-summary
<R1>dis ospf routing
<R1>dis ospf lsdb

​

Step 6 Configure area 1 as an NSSA

<R4>display ospf routing
<R5>display ospf routing

[R4-ospf-1-area-0.0.0.1]nssa
[R5-ospf-1-area-0.0.0.1]nssa

<R5>display ospf routing
<R5>display ospf lsdb
<R4>display ospf routing

Step 7 Observe the impact of the NSSA on OSPF.

<R4>display ospf
<R4>display ospf lsdb nssa 10.0.5.0
<R4>display ospf lsdb ase 10.0.5.0

ospf网络类型

根据不同的二层链路类型
