一份一类 LSA 中会包含多个 link, 每个 link 描述了该设备在本区域内连接的一个网络或节点
1.P2P:
OSPF 在串行链路中会使用两个 link 来描述该链路信息,其中 stubnet link 用来描述链路的网络信息,P2P 用来描述所连接的节点信息
Link type: 链路类型 P2P
Link ID: 所连接节点的 RID
Link Data: 表示本设备接口的 IP 地址
Metric: 度量值,表示开销
2.stubnet 表示 OSPF 设备连接到一个末节网络,描述网络信息
Link type: 链路类型 stubnet
Link ID: 表示该设备所连接的网络号
Link Data: 表示该设备所连接的网络掩码
Metric: 表示到达此网络的开销
3.transnet: 描述了 OSPF 设备到达 DR (伪节点) 的开销情况
Link ID: DR 的接口 IP 地址
Link Data: 该设备接口 IP 地址
Metric: 表示到达 DR (伪节点) 的开销

区域间路由计算
OSPF 只能在区域内传递 LSA1,LSA2, 所以在区域间 ABR 设备会将路由表中的路由信息以 LSA3 的形式传入到其他区域,从而让其他区域的路由器可以计算相应的路由信息.
Network summary LSA
LSA3: 每个 3 类 LSA 实际上就是一个网络信息,ABR 将路由信息转换成 LSA3 并且描述到达网络的开销,其他的 OSPF 设备根据 LSA3 以及自身到达 ABR 的开销值,计算得到区域间路由,LSA3 只在生成的区域内传递,如果需要传入下一个区域,需要另一个 ABR 重新计算生成 LSA3.
