Note:
If it is possible to define a default router (option sometimes available), to which any
packet may be transmitted which cannot be routed using the routing table.
The following figure shows an example of an IP network and routing tables associated with two
equipment types. It shall be noted that each port of the onboard routing function corresponds to
a different SUBNET.
