问题 A router has learned three possible routes that could be used to reach a destination network． One route is from EIGRP and has a composite metric of 20514560． Another route is from OSPF with a metric of 782．The last is from RIPv2 and has a metric of 4． Which route or routes will the router install in the routing table?
选项 A、        the OSPF route
B、        the EIGRP route
C、        the RIPv2 route
D、        all three routes
E、        the OSPF and RIPv2 routes
答案B
解析 考点：考查路由条目进入路由表的原则：最优路由才能进入。去往同一目的的多条路由，先比较AD值，AD值小者优先；AD值一直则比较metric值。
EIGRP 90
OSPF 110
RIP 120
