所谓路由协议的收敛，就是指路由协议发现网内其他路由器并交换路由条目，直至所有路由条目都交换完成的过程。

OSPF协议在收敛后，应该保证所有路由器借口都在本地LSDB中。这就意味着网内所有路由器的LSDB在网络收敛后都应该是一样的。每一台路由器都知道网内所有路由链路。

在网络收敛后，协议使用SPF算法，每台路由器都生成一个以自己为根节点的最短路径优先树。路由路径由此生成。

OSPF协议维护着3张表，即邻居表，LSDB（拓扑表）和路由表。这三张表按顺序依次建立。

通过HELLO包，OSPF协议发现邻居路由--> 通过LSA的交换完成LSDB --> 用过FPS算法得到路由表

为了显示收敛的大致过程，这里显示了追踪HELLO包和ospf event可以做一个大体的了解，

拓扑如下：

Fig1，演示收敛过程的拓扑

这里用G口是因为以太口是广播型网络，路由器之间必须选举DR和BDR来形成邻接关系。

以下红字部分为注释

在网络建立之后，在R1上使用reset ospf 1 process重置ospf协议使其再次收敛，以下为R1的的状态显示

 OSPF 1: Intf 1.1.1.1 Rcv UnloopInd State Loopback -> Down.

R1发送第一个HELLO包，到224.0.0.5组播地址。RFC上说第一个HELLO包应该是广播形式发送，可见厂商并没有完全按照RFC上来实现。发送自己的RID1.1.1.1，DR和BDR均为0.0.0.0，这意味着这是一台新加入的路由器，其并不知道网络中的选举情况。但有材料上说在初次选举时，DR和BDR值均为自己，但H3C看起来并没有这么做。

满足建立邻居的条件

1. 广播链路两端的IP子网/子网掩码匹配

2. HELLO包死亡时间匹配

3. 认证类型匹配

4. 认证密钥匹配

5. 区域ID匹配

6. 其他类型的匹配，比如

当R1看见自己的RID1.1.1.1出现在R3的回应中时，认为R3已经收到了R1的HELLO包，并且参数互相匹配。R1和R3互相都存在于对方的邻居表内，此时的状态由init变为2way关系。

此时R1与全部路由器均形成了2way关系。但是4.4.4.4和3.3.3.3是DR与BDR，而2.2.2.2为DRother关系。在广播类型中，路由器与DR和BDR形成邻接关系，与DRother保持2way关系，所以与2.2.2.2仍然是2way，但与3.3.3.3和4.4.4.4变成ExStart关系。

在ExStart状态下，协商参数，包括Master/Slave和DBD的seq_number。其中只有Master有能力增加交换DBD时的seq_number。

路由器通过向邻居发送DBD包来描述LSDB的摘要，每个DBD包都有一个显式的seq_number。

OSPF 1: Nbr 15.15.15.3 Rcv NegotiationDone State ExStart -> Exchange.

Loading状态表示DBD包已经完成交换，路由器根据DBD的描述信息，发送LSR链路状态请求数据包以取得自己没有的LSA。邻居路由器通过回应LSU数据包来更新LSDB。在LSU中包含了数条LSA。

完全邻接状态是交换链路状态之后的最终状态。一般情况下，成功交换完成的OSPF都应该停留在这个状态，但只有一个例外。在有DR和BDR存在的网络中，DRother路由器仅仅与DR和BDR互为邻接状态，DRother之间保持在2way状态。
