6.查看邻居关系

（1）

[r3]int t0/0/0
[r3-Tunnel0/0/0]ospf network-type broadcast 
[r5]int t0/0/0
[r5-Tunnel0/0/0]ospf network-type broadcast 
[r6]int t0/0/0
[r6-Tunnel0/0/0]ospf network-type broadcast
[r7]int t0/0/0
[r7-Tunnel0/0/0]ospf network-type broadcast 
（修改R5/6/7优先级）
[r5-Tunnel0/0/0]ospf dr-priority 0
[r6-Tunnel0/0/0]ospf dr-priority 0
[r7-Tunnel0/0/0]ospf dr-priority 0

（2）

（3）

（4）

7.查看路由

（1）

（将RIP两条路由重发布）
[r1]display ip routing-table protocol ospf

（2）

（导入双向重发布）
[r9]ospf 1
[r9-ospf-1]import-route ospf 2
[r9]ospf 2
[r9-ospf-2]import-route ospf 1

8.汇总路由

[r3]ospf 1
[r3-ospf-1]area 1
[r3-ospf-1-area-0.0.0.1]abr-summary 172.16.32.0 255.255.224.0
[r6]ospf 1

[r9]ospf 2
[r9-ospf-2]undo import-route ospf 1

（R9为R10发缺省路由）

[r9]ospf 2
[r9-ospf-2]default-route-advertise

10.全网可达
