摘　　要：公司企业专网长期采用OSPF单区域的部署的方式,由于企业专网内交换机数量较大、网段较多,所以会泛洪大量的LSA,进而产生比较大的LSDB,由于所有交换机都在一个区域内,所以各交换机不论性能高低都存储维护一个完全相同的LSDB,因此这种单一OSPF区域的配置会导致OSPF路由收敛性能下降,增加交换机CPU处理负荷。通过划分多OSPF区域的方式,LSA过滤方式和LSA汇聚等方式优化网络部署,有助于加速收敛,并减少OSPF网络中的开销。The corporate private network uses OSPF single-area deployment for a long time. Because there are a large number of switches and a large number of network segments in a private network, a large number of LSAs are flooded, resulting in a relatively large LSDB. Because all switches are in one area, all switches maintain an identical LSDB regardless of the performance. Therefore, the configuration of a single OSPF area will cause the OSPF route convergence performance to decrease, and increase the CPU load on the switch. By dividing multiple OSPF areas, LSA filtering and LSA aggregation, we can optimize network deployment, which helps to accelerate convergence and reduce the overhead in OSPF networks.
