路由器首要匹配主网络号，假如主网络号存在，就持续匹配子网号，且不考虑缺省路由，假如子网无法匹配，丢弃数据包，在分类路由下，路由器以为认识所有主网络下的悉数子网，并使用ICMP回来一个不可达回答。假如主网络号不存在，使用缺省路由。

(The router first matches the main network number. If the main network number exists, it continues to match the subnet number, and does not consider the default route. If the subnet cannot be matched, the packet is discarded. All subnets are returned and an unreachable answer is returned using ICMP. If the major network number does not exist, the default route is used.)
