You're Already There: Directly Connected Routes in R1's and R2's Routing Tables

[View full size image]

Routers always add routes for directly connected subnets and networks, as long as the interface is both configured and working. Although it is important that the routers include the directly connected subnets in their routing tables, if that's all R1 and R2 know about, then they do not know enough routes in their routing table. For instance, if Hannah tries to send a packet to the web server (150.1.3.3), then R1 will not have a route that matches the packet's destination address, and R1 will simply discard the packet.
