华为路由器OSPF配置
转自华为路由器OSPF配置
配置拓扑
按照拓扑图上配置ospf的三个区域，相互学习到路由并查看每个路由器的LSDB和相关LSA信息，AR4与AR6分别扮演ASBR角色并将自己的环回接口网络重分布进ospf网络中，AR6的外部路由使type1（AR4的使用默认的type2）分布进ospf，并查看LSA5。
AR1的配置
interface GigabitEthernet0/0/0
ip address 12.1.1.1 255.255.255.0
#
interface GigabitEthernet0/0/1
ip address 13.1.1.1 255.255.255.0
#
ospf 1 router-id 1.1.1.1 ospf的r-id
area 0.0.0.0 创建area0
network 12.1.1.1 0.0.0.0 在area0中宣告属于area0区域的接口（允许该接口在area0收发ospf报文）

ip address 56.1.1.6 255.255.255.0
#
interface LoopBack0
ip address 6.6.6.6 255.255.255.255
#
ospf 1 router-id 6.6.6.6
import-route direct type 1 重分布直连路由到ospf中，类型为type1（类型区别在于路由的metric不同，type1的cost大）
area 0.0.0.2
network 56.1.1.6 0.0.0.0
#
查看ospf的LSDB数据库，在AR1上查看，做为ABR应该有2个区域的lsa1-3信息以及外部重分布的lsa5和到达asbr的lsa4
