(实验)-多点双向重分布

实验配置:

实验拓扑如上图, 两个路由选择域, 在R2, R3上做路由的双向重分布, 使每个区域的路由器都可以达到共识.

实验目的:

解决在多点重分布时出现路径的不优问题.

R2配置:

!

router ospf 1

router-id 2.2.2.2

log-adjacency-changes

redistribute rip metric 10000 metric-type 1 subnets

network 192.1.12.0 0.0.0.255 area 0

!

router rip

version 2

redistribute ospf 1 metric 5

network 2.0.0.0

network 192.2.24.0

no auto-summary

!

ip classless

no ip http server

!

!

R3配置:

!

router ospf 1

router-id 3.3.3.3

log-adjacency-changes

redistribute rip metric 10000 metric-type 1 subnets

network 192.1.13.0 0.0.0.255 area 0

!

router rip

version 2

redistribute ospf 1 metric 5

network 3.0.0.0

network 192.2.35.0

no auto-summary

!

ip classless

no ip http server

!

!

R2 先双向重分布, 然后R3再双向重分布.

*红色路由不优, 红色条目为以下RIPv2的路由, 直接通过RIP就可以到达, 现在反而通过OSPF学到从RIP重分布进来的这些条目.
