Routing
Routing is the method by which the host or gateway decides where to send the datagram.
Routing is the task of finding a path from a sender to a desired destination. It may be able to
send the datagram directly to the destination, if that destination is on one of the networks that
are directly connected to the host or gateway. However, what if the destination is not directly
reachable? The host or gateway will attempt to send the datagram to a gateway that is nearer
to the destination. The goal of a routing protocol is very simple: It is to supply the information
that is needed to do routing. This chapter describes how to configure the IPv4 unicast routing
on the T3700G-52TQ.

Interface
Interface is a virtual interface in Layer 3 mode and mainly used for realizing the Layer 3
connectivity between VLANs or routed ports. Each VLAN interface is corresponding to one
VLAN. Each routed port is corresponding to one port. Loopback Interface is purely software
implemented. Interface has its own IP address and subnet mask to identify the subnet it
belongs to, and it works as the gateway of the subnet to forward Layer 3 IP packets.
