CCNP(BSCI)實驗：OSPF綜合實驗

實驗要求：
1.R1上重分佈EIGRP100的路由進入到EIGRP125和OSPF域，發進EIGRP125要求彙總（R1 loopback 宣告進OSPF域）

2.R5上必定要經過彙總路由到達EIGRP100，到達EIGRP域要優選R1這條路

3.R2上單點雙向重分佈（保證5能夠到ospf域，ospf能夠到達EIGRP 125），要求發進EIGRP的時候考慮eigrp 100的明細路由（需求 2）發到OSPF的時候要考慮那條彙總路由

4.Area23要求優化LSA（考慮R2作重分佈），保證R3具備可達性（R2發默認路由）

5.R3重分佈OSPF到RIP，保證R4能夠經過OSPF到達全網（考慮R2給R3的默認路由）

6.R5重分佈EIGRP到RIP（思考若是R3首先重分佈路由給R4,R5如何重分佈EIGRP給R4）

7.保證R4不存在次優路徑，能夠經過OSPF和EIGRP同時到達的區域，優選EIGRP
