IP routing
The TransPortdevice uses IP routes to decide where to send a packet it receives for a remote
network. The process for deciding on a route to send the packet is as follows:
1. The device examines the destination IP address in the IP packet, and looks through the IP
routing table to find a match for it.
2. If it finds a route for the destination, it forwards the IP packet to the configured IP gateway or
interface.
3. If it cannot find a route for the destination, it uses a default route.
4. If there are two or more routes to a destination, the device uses the route with the longest
mask.
5. If there are two or more routes to a destination with the same mask, the device uses the route
with the lowest metric.
Configure general IP settings
Configuring general IPsettings is one of the building blocks of setting up IProuting.
Optional configuration items
n The IP hostname. This hostname identifies the TLR device on IP networks. It is an unqualified
hostname. The default setting for the device is <model>-%s which expands to serial number
for the device.
n The administrative distance settings for connected and static routes. Administrative distance
settings rank the type of routes, from the most to least preferred. When there are two or more
routes to the same destination and mask, the route with the lowest metric is used. By default,
routes to connected networks are preferred, with static routes being next. The administrative
distance for each route type is added to the route’s metric when it is added to the routing
table. Configuring the administrative distance of a particular route type can alter the order of
use for the routes. The two administrative distance settings are:
l Administrative distance for connected network routes. The default value is 0.
l Administrative distance for static routes. The default value is 1.
Web
In the web interface, general IPsettings are configured as part of configuring a LANor WAN. See
Configure a LAN and Configure a Wide Area Network (WAN).
