实验拓扑图:
实验要求:
要求4配置:
R1:int g/0/0
ospf dr-priority 0
【将优先级修改为0或者将网络类型修改为P-2-P后,将不能选举DR、BDR】
要求5的配置:
R3:ospf 1
a 1
nssa
nssa no-summary
R4:ospf 1
a 1
nssa
nssa no-summary
配置nssa前R4的LSDB:
修改后的LSDB:
要求9的配置:
R3:int g/0/1
ospf dr-priority 100
【修改接口优先级即可,优先级为0就失去参加选举DR的资格。
优先级最大为DR,优先级相等时,看route-id。如果,将接口优先级修改之后,
还是不能顺利成为DR,此时可重启OSPF进程,或者shutdown掉接口再no shutdown。
