Adding Ip Routes; Table 6-1 Ip Routing Table - ZyXEL Communications Prestige 623 series User Manual

Prestige 623 Series Dual-link ADSL Router
The IP Route Table displays a row for each existing route. These include routes that were predefined on
the device, routes you may have added, and routes that the device has identified automatically through
communication with other devices. The routing table should reflect a default gateway, which directs
outbound Internet traffic to your ISP. This default gateway is shown in the row containing destination
address 0.0.0.0.
The following table defines the fields in the IP Route Table.
FIELD
Destination This field specifies the IP address of the destination computer. The destination can be
specified as the IP address of a specific computer or an entire network. It can also be
specified as all zeros to indicate that this route should be used for all destinations for
which no other route is defined (this is the route that creates the default gateway).
Netmask This field indicates which parts of the destination address refer to the network and which
parts refer to a computer on the network. Refer to IP Address, Network Masks and
Subnets appendix for more information. The default gateway uses a netmask of 0.0.0.0.
NextHop This field specifies the next IP address to send data to when its final destination is that
shown in the destination column.
IFName This field displays the name of the interface on the device through which data is forwarded
to the specified next hop.
Route This field displays whether the route is direct or indirect. In a direct route, the source and
Type destination computers are on the same network, and the router attempts to directly deliver
the data to the computer. In an indirect route, the source and destination computers are
on different networks, and the router forwards data to a device on another network for
further handling.
Route This field displays how the route was defined. Dynamic indicates that the route was
Origin created automatically or predefined by your ISP or the manufacturer. Routes you create
are labeled Local. Other routes can be created automatically (using RIP, as described in
later chapter), or defined remotely through various network management protocols (LCL
or ICMP).
