OSPF配置实验之特殊区域totally stub
1、特殊区域totally stub解析区域类型作用默认路由备注命令
stub过滤LSA4、LSA5ABR默认下发3类默认路由，seed cost值为1本区域所有路由器都必须配置成stub，否则邻居起不来，且不能包含ASBR
area 2 stub
area 2 default-cost x
totally stub过滤LSA3、LSA4、LSA5ABR默认下发3类默认路由，seed cost值为1本区域所有路由器都必须配置成stub，否则邻居起不来，且不能包含ASBRarea 2 stub no-summary
2、实验拓扑3、实验配置R1配置interface Loopback0 ip address 1.1.1.1 255.255.255.0interface Serial0/0 ip address 12.1.1.1 255.255.255.0router ospf 110 router-id 1.1.1.1 network 12.1.1.0 0.0.0.255 area 2
R2配置interface Loopback0 ip address 2.2.2.2 255.255.255.0interface Serial0/0 ip address 12.1.1.2 255.255.255.0interface Serial0/1 ip address 23.1.1.2 255.255.255.0router ospf 110 router-id 2.2.2.2 network 12.1.1.0 0.0.0.255 area 2 network 23.1.1.0 0.0.0.255 area 0
R3配置interface Loopback0 ip address 3.3.3.3 255.255.255.0interface Serial0/0 ip address 34.1.1.3 255.255.255.0interface Serial0/1 ip address 23.1.1.3 255.255.255.0router ospf 110 router-id 3.3.3.3 network 23.1.1.0 0.0.0.255 area 0 network 34.1.1.0 0.0.0.255 area 1
R4配置interface Loopback0 ip address 4.4.4.4 255.255.255.0interface Serial0/0 ip address 34.1.1.4 255.255.255.0interface Serial0/1 ip address 45.1.1.4 255.255.255.0router ospf 110 router-id 4.4.4.4 redistribute rip subnets network 34.1.1.0 0.0.0.255 area 1
R5配置interface Loopback0 ip address 5.5.5.5 255.255.255.0interface Serial0/1 ip address 45.1.1.5 255.255.255.0 serial restart-delay 0router rip version 2 network 5.0.0.0 network 45.0.0.0 no auto-summary
4、实验验证过滤LSA3、LSA4、LSA4配置totally stub前配置totally stub后
ABR下放3类默认路由
配置totally stub前
配置totally stub后
