The Switch/Router
Published in James Aweya, Switch/Router Architectures, 2019
In topology-based forwarding, the route processor runs the routing protocols to create the routing tables. Entries in the routing table can also be created manually as static routes. The most relevant information needed for packet forwarding is distilled from the routing table to generate the more compact forwarding table. The forwarding table contains the same information needed to forward packets as the routing table, the only difference is it contains only the information that can be used directly by a forwarding engine in forwarding packets—it excludes all other information not needed for forwarding.
Internet Layer

The default route, also referred to as gateway of last resort, comprises a single static route to where a router should forward all packets whose destination IP address is outside its own internal network. When a router is only connected to another router, the default route configuration is typically utilized. A common situation is when the router only has two interfaces: one connected to a LAN and another interface connected to another router. In this case, all packets received from the LAN, whose destination is not another host outside the LAN, should be forwarded to the other router (default route).

Finally, we use the previous results to compare the static, no re-routing, continuous re-routing and ideal prediction strategies, detailed in sections “Static Route Planning, No re-routing route planning, Continuous re-routing route planning, Ideal prediction based route planning” respectively.
