CCNP(BSCI)实验：OSPF综合实验（ccnp实验题）

2.R5上一定要通过汇总路由到达EIGRP100，到达EIGRP域要优选R1这条路

3.R2上单点双向重分布（保证5可以到ospf域，ospf可以到达EIGRP 125），要求发进EIGRP的时候考虑eigrp 100的明细路由（需求 2）发到OSPF的时候要考虑那条汇总路由

4.Area23要求优化LSA（考虑R2做重分布），保证R3具有可达性（R2发默认路由）

5.R3重分布OSPF到RIP，保证R4可以通过OSPF到达全网（考虑R2给R3的默认路由）

6.R5重分布EIGRP到RIP（思考如果R3首先重分布路由给R4,R5如何重分布EIGRP给R4）

7.保证R4不存在次优路径，可以通过OSPF和EIGRP同时到达的区域，优选EIGRP
