The Route Table Configuration page contains the following options/fields:
Menu Options/Fields Entry Description
Route001-Route008
(256)
(The 8 currently
displayed routes, up to
256 can be defined)
1-8 Route Table allows user to define how packets the IP
M odule receives are routed. Defining an entry in this table is
similar to using 'route add' command of machines that
support that command. For each route, the user must define:
1. A name assigned by the user to reference the route.
The assigned name cannot contain any whitespace
and must be unique.
2. The destination address of an IP packet of interest.
The number of network addresses that are governed by the
selected destination entry, i.e., subnet mask.
The Next Hop IP address. This is the IP where the packet will
be routed for further processing. The Next Hop IP Address
for traffic to be sent over the satellite will be the desired
HDLC address.
Point-to-Point – no HDLC address
Small Network - 0x1 – 0xFE
Large Network – 0x1 – 0xFFFE
Also, a route can be defined to have IP M odule send traffic
to another IP address on the same subnet as the Ethernet
interface.
Optionally: If the user enters a multicast address (224.0.0.0-
239.255.255.255) as the destination IP address, then the
following parameters will be requested:
Route MultiCast packets from Ethernet to Satellite? [y/n]
The option allows the user to specify if multicast packets that
match the provided IP address will be routed from the
Ethernet to Satellite. “No” means that the packets will be
discarded.
Route MultiCast packets from Satellite to Ethernet? [y/n]
The option allows the user to specify if multicast packets that
match the provided IP address will be routed from the
Satellite to Ethernet. “No” means that the packets will be
discarded.
Multicast Routes always have a subnet length of 32 and the
next hop is 0.0.0.0 because it is not applicable.
Note: The IP M odule does allow the specification of one
and only one default route. Destination IP = 0.0.0.0
Subnet Length = 0. The default route can be defined
to send traffic to either the Satellite or Ethernet
interface.
This will cause all packets that do not match any
other route to be sent to the destination you have
defined for further processing.
