Menu Options/Fields Entry Description
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 the CDM-IP send
traffic to another IP address that is 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 CDM-IP 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.
Base B The Route Table menu allows the user to view up to 8
different routes per screen. To allow editing on any of the
256 entries that can be defined, the user can select a
base address to control which 8 routes are displayed. For
example, if the user wants to edit Routes 32-40, then a
Base value of 32 should be defined.
Delete Route D Route Name to delete.
Display P Displays all of the routes that are currently defined in the
system. This will include automatically generated routes
that are provided to simplify provisioning of the system.
The information displayed is: Route Name,
DestIP/SnetBits, Next Hop, HDLC, and Flags.
PerRoute E Enter to enable Header Compression, Payload
Compression or 3xDES Encryption on a Per Route basis.
