实验指南：OSPF之-----多区域路由，验证

实验指南

 

 

Configure an IP network, as depicted in Figure 12−14, by using OSPF as the routing protocol and 2002 as the Autonomous System ID.

 

Configure the Frame Relay network as a point−to−point network between dental_ho and the router fillings. Use a Frame Relay multipoint network between the dental_ho, crowns, and root_canals routers.
 
Configure all the OSPF areas as denoted in the diagram. Area 10 is to be configured as a NSSA area.Inject a default route into the dental_ho router pointing all Internet traffic toward the network 128.10.1.0/24. Propagate the default route within the OSPF domain.
 
Configure Type 2 authentication in Area 200.The root_canals router has a T1 to the dental_ho router. Configure the network so that the pain_center
router will use the T1 of root_canals over the crowns router's 64−kbps link when accessing any networks across the WAN.
