问题描述
组网概述 两台S7700直连,S7700A为某局点维护设备,S7700B为非该局点维护设备,不能进行查看
组网拓扑图 配置信息 S7700A: interface GigabitEthernet0/0/1 port link-type access port default vlan 2 # interface vlanif 2 ip address 10.1.0.1 24 # ospf 1 area 0.0.0.0 network 10.1.0.1 0.0.0.0 故障现象 S7700A上能学习到对端发布的默认路由的LSA,但默认路由路由不加表
告警信息
处理过程
1. 查看ospf路由表,默认路由未加表 <Huawei>display ospf routing OSPF Process 1 with Router ID 10.1.0.1 Routing Tables Routing for Network Destination Cost Type NextHop AdvRouter Area 10.1.0.0/24 1 Transit 10.1.0.1 10.1.0.1 0.0.0.0 Total Nets: 1 Intra Area: 1 Inter Area: 0 ASE: 0 NSSA: 0 2.查看ospf lsdb信息,学习到了默认路由的LSA <Huawei>display ospf lsdb OSPF Process 1 with Router ID 10.1.0.1 Link State Database ………… AS External Database Type LinkState ID AdvRouter Age Len Sequence Metric External 0.0.0.0 10.1.0.2 1262 36 80000002 1 3.查看ospf 外部路由的lsdb信息,默认路由的下一跳为S7700A的地址 [Huawei]display ospf lsdb ase OSPF Process 1 with Router ID 10.1.0.1 Link State Database Type : External Ls id : 0.0.0.0 Adv rtr : 10.1.0.2 Ls age : 97 Len : 36 Options : E seq# : 80000002 chksum : 0x179f Net mask : 0.0.0.0 TOS 0 Metric: 1 E type : 2 Forwarding Address : 10.1.0.1 Tag : 1
