z If there is no default route and the destination address of the packet fails to match any entry in the
routing table, the packet will be discarded and an ICMP packet will be sent to the source to report
that the destination or the network is unreachable.
The network administrator can configure a default route with both destination and mask being 0.0.0.0.
The router forwards any packet whose destination address fails to match any entry in the routing table
to the next hop of the default static route.
