OSPF配置常用命令知识总结
OSPF配置常用命令知识总结
1.display ospf abr-asbr 命令用来显示OSPF的区域边界路由器和自治系统边界路由器信息。
[R3]dis ospf abr-asbr
OSPF Process 1 with Router ID 20.1.3.0
Routing Table to ABR and ASBR
Rt Type Destination Area Cost Nexthop Type
Intra-area 30.3.6.0 0.0.0.0 3 192.168.34.4 ABR
2.display ospf lsdb 命令用来显示OSPF的链路状态数据库（LSDB）信息。
[R3]display ospf lsdb
OSPF Process 1 with Router ID 20.1.3.0
Link State Database
Area: 0.0.0.0

5.配置网络接口类型，影响DR的选举
[R3] interface GigabitEthernet 0/0/0
[R3-GigabitEthernet0/0/0] ospf network-type p2p
6.配置所在网段的接口，影响DR的选举
[R3] interface GigabitEthernet 0/0/0
[R3-GigabitEthernet0/0/0] ospf dr-priority 0
7.配置路由器所在接口的cost，影响路由的选择
[R3]interface GigabitEthernet 0/0/0
[R3-GigabitEthernet0/0/0]ospf cost 45
8.配置路由器间的Hello计时器时长
[R3]interface GigabitEthernet 0/0/0
[R3-GigabitEthernet0/0/0]ospf timer hello 4
9.配置路由器之间的Dead计时器时长
[R3]interface GigabitEthernet 0/0/0
[R3-GigabitEthernet0/0/0]ospf timer dead 33
