4.7 修改OSPF参考带宽

1.查看R1的OSPF路由信息的COST值

<R1>display ip routing-table protocol ospf
Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface
        2.2.2.2/32  OSPF    10   1           D   12.1.1.2        GigabitEthernet0/0/0
        3.3.3.3/32  OSPF    10   2           D   12.1.1.2        GigabitEthernet0/0/0
        4.4.4.4/32  OSPF    10   3           D   12.1.1.2        GigabitEthernet0/0/0
       23.0.0.0/8   OSPF    10   2           D   12.1.1.2        GigabitEthernet0/0/0
       34.0.0.0/8   OSPF    10   3           D   12.1.1.2        GigabitEthernet0/0/0

2.修改R1的OSPF参考带宽，查看OSPF路由信息的COST值

[R1]ospf 1
[R1-ospf-1]bandwidth-reference 10000
[R1-ospf-1]display ip routing-table protocol ospf
Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface 
2.2.2.2/32  OSPF    10   10          D   12.1.1.2        GigabitEthernet0/0/0
        3.3.3.3/32  OSPF    10   11          D   12.1.1.2        GigabitEthernet0/0/0
        4.4.4.4/32  OSPF    10   12          D   12.1.1.2        GigabitEthernet0/0/0
       23.0.0.0/8   OSPF    10   11          D   12.1.1.2        GigabitEthernet0/0/0
       34.0.0.0/8   OSPF    10   12          D   12.1.1.2        GigabitEthernet0/0/0

3.查看OSPF的LSDB信息， Sum-Net是三类LAS，用于描述区域间路由

[R1-ospf-1]display ospf lsdb
  OSPF Process 1 with Router ID 1.1.1.1
                 Link State Database 
                         Area: 0.0.0.1
 Type      LinkState ID    AdvRouter          Age  Len   Sequence   Metric
 Router    2.2.2.2         2.2.2.2            705  48    80000004       0
 Router    1.1.1.1         1.1.1.1            119  48    80000008      10
 Network   12.1.1.1        1.1.1.1            702  32    80000002       0
 Sum-Net   23.0.0.0        2.2.2.2            723  28    80000001       1
 Sum-Net   3.3.3.3         2.2.2.2            503  28    80000001       1
 Sum-Net   34.0.0.0        2.2.2.2            495  28    80000001       2
 Sum-Net   4.4.4.4         2.2.2.2            493  28    80000001       2
