Simple Module RoutingTable

Package: inet.networklayer.ipv4
File: src/networklayer/ipv4/RoutingTable.ned

C++ definition

Stores the routing table. (Per-interface configuration is stored in InterfaceTable.)

For hosts, the routerId module parameter should be empty (""), in which case the loopback IP address will be set to 127.0.0.1/8. For routers which have a routerId set, the loopback address will be set to routerId. (See also RFC 2072 "Router Renumbering Guide".)

RouterId may also be set to the string "auto", in which case the highest interface address will be chosen as routerId; the loopback address will remain 127.0.0.1/8.

The routing table is read from a file (parameter routingFile); the file can also fill in or overwrite interface settings. The file format is documented here.

Note that many protocols don't require routerId to be routable, but some others do -- so it is probably a good idea to set up routable routerIds.

This module has no gates; all functionality can be accessed via member functions of the C++ module class. For detailed info, please see the C++ documentation of the class (Doxygen).

Used in compound modules:

Name Type Description
BurstHost compound module

Definition of an IP node with a transport generator that connects to IP directly, without TCP or UDP.

ExtRouter compound module

External router.

LDP_LSR compound module

An LDP-capable router.

MFMobileHost compound module

Models a mobile host with a wireless (802.11b) card in ad-hoc mode. This model contains the Mobility Framework's 802.11 implementation, Nic80211, and IP, TCP and UDP protocols. The mobility model can be dynamically specified with the mobilityType parameter.

MobileHost compound module

Models a mobile host with a wireless (802.11b) card in ad-hoc mode. This model contains the new IEEE 802.11 implementation, Ieee80211Nic, and IP, TCP and UDP protocols. The mobility model can be dynamically specified with the mobilityType parameter.

OSPFRouter compound module

An OSPFv2 router.

Router compound module

IP router.

RSVP_LSR compound module

An RSVP-TE capable router.

RTPHost compound module (no description)
StandardHost compound module

IP host with SCTP, TCP, UDP layers and applications.

StandardHostWithDLDuplicatesGenerator compound module

IP host with SCTP, TCP, UDP layers and applications AND PPPInterfaceWithDLDuplicatesGenerator.

StandardHostWithDLThruputMeter compound module

IP host with SCTP, TCP, UDP layers and applications AND PPPInterfaceWithDLThruputMeter.

StandardHostWithULDropsGenerator compound module

IP host with SCTP, TCP, UDP layers and applications AND PPPInterfaceWithULDropsGenerator.

StandardHostWithULThruputMeter compound module

IP host with SCTP, TCP, UDP layers and applications AND PPPInterfaceWithULThruputMeter.

TCPSpoofingHost compound module

IP host with TCPSpoof in the application layer.

WirelessHost compound module

Models a host with one wireless (802.11b) card in infrastructure mode. This module is basically a StandardHost with an Ieee80211NicSTA added. It should be used in conjunction with WirelessAP, or any other AP model which contains Ieee80211NicAP.

WirelessHostSimplified compound module

Models a host with one wireless (802.11b) card in infrastructure mode, but using a simplified NIC that does not support handovers. This module is basically a StandardHost with an Ieee80211NicSTASimplified added. It should be used in conjunction with WirelessAPSimplified, or any other AP model which contains Ieee80211NicAPSimplified.

Parameters:

Name Type Default value Description
routerId string "auto"

for routers, the router id using IP address dotted notation; specify "auto" to select the highest interface address; should be left empty ("") for hosts

IPForward bool true

turns IP forwarding on/off

routingFile string ""

routing table file name

Properties:

Name Value Description
display i=block/table
