Switch and Router Technology - 25 - OSPF Multi-Area Configuration
2022-08-11 04:52:00 【w Spicy little prince】
目录
一、OSFP多区域
1.1 multi-regional purposes
实现大型网络环境
划分区域后,Achieve single-area network convergence,从而加快网络收敛速度
1.2 Multi-regional benefits
改善网络,更具有扩展性
快速网络收敛
减少了路由表
减少了LSU(链路状态更新包)流量
1.3 OSPF通信流量
within the area:域内通信量
DR、BDR、内部路由器(All router interfaces belong to the same area)
不同区域间:Inter-domain communication traffic
ABR(区域边界路由器) Router interfaces belong to different areas
External communication traffic(与其他自治系统):外部通信量
ASBR(自治系统边界路由器) All interfaces of the router belong to different autonomous systems
1.4 区域分类
骨干区域
Area 0
非骨干区域
标准区域
末梢区域
完全末梢
非纯末梢
1.5 链路状态通告(LSA)
6The link status is passed
类型1:路由器的LSA,Mainly issued by routers in the area(内部路由器)、
类型2:网络LSA,由区域内的DR发出
类型3:网络汇总LSA,由ABR发出
类型4:ASBR汇总LSA,由ABR发出
类型5:AS外部LSA,由ASBR发出
类型6:Outside of the impure peripheral regionLSA
1.6 多区域配置实例
Complete the above topology,and configured for each interfaceIP,子网掩码
The multi-zone configuration is as follows
R0
Router(config)#
Router(config)#router ospf 10
Router(config-router)#router
Router(config-router)#router-id 2.2.2.2
Router(config-router)#network 192.168.10.0 0.0.0.255 area 0
R1
Router(config)#
Router(config)#router ospf 10
Router(config-router)#router
Router(config-router)#router-id 1.1.1.1
Router(config-router)#network 192.168.10.0 0.0.0.255 area 0
Router(config-router)#network 192.168.20.0 0.0.0.255 area 1
R2
Router(config)#
Router(config)#router ospf 10
Router(config-router)#router
Router(config-router)#router-id 3.3.3.3
Router(config-router)#network 192.168.20.0 0.0.0.255 area 1
查看R0路由表
新增一条O IA 区域间ospf
O is an intra-area route
实例二
Check the routing table status,Three pieces of inter-area routing information are generatedO IA
1.7 思考
PC1 到PC2 有两条路径,会怎么走
形成负载,Both paths are possible
If the default path is deleted,又会怎么走
go the other way
If you give him the path to take,Bandwidth is reduced,又会怎么走
Wide bandwidth
