本文涉及OSPF路由器配置，包括DR/BDR选举、接口认证、路由宣告及IP分配。R3在r3456网络中未设置BDR，R1和R4间OSPF邻居建立成功但全网可达性受限。此外，DHCP服务器配置了IP地址池并实现了静态绑定。部分设备间ping测试显示通信不稳定。最后，OSPF的area1区域采用明文认证，area2使用混合加密方式。

1.r3456之间只有r3为没有bdr

 Router ID: 5.5.5.5        Address: 123.1.1.3       
   State: 2-Way  Mode:Nbr is  Master  Priority: 0
   DR: 123.1.1.1  BDR: None   MTU: 0    
   Dead timer due in 31  sec 
   Retrans timer interval: 0 
   Neighbor is up for 00:00:00     
   Authentication Sequence: [ 0 ]

2.保证更新安全加快收敛速度
