实验指南：EIGRP之-----缺省路由，路由过滤

2007-04-18 17:58:45

实验指南EIGRP

Configure an IP network as depicted in Figure using EIGRP as the routing protocol and 2001 as the Autonomous System ID.

Configure the Frame Relay network as a point−to−point network among all the routers. Do not create a multipoint network.

Do not allow any other shops to see the subnet 172.16.3.0/24 on the barneys router.

Inject a default route into the solar_bucks router pointing all traffic to the internet_router.

The direct Frame link between solar_bucks and g_and_s router is very expensive. Configure EIGRP so that traffic from g_and_s will go first to barneys and then to solar_bucks. If the PVC between barneys and g_and_s drops, traffic will flow directly from g_and_s to solar_bucks.
