Simple Module RoutingTable

File: Network/IPv4/RoutingTable.ned

C++ definition: click here

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).

Usage diagram:

The following diagram shows usage relationships between modules, networks and channels. Unresolved module (and channel) types are missing from the diagram. Click here to see the full picture.

Used in compound modules:

If a module type shows up more than once, that means it has been defined in more than one NED file.

StandardHost

IP host with TCP, UDP layers and applications.

QuaggaRouter

Quagga-based IP router.

MobileHost

Models a mobile host with a wireless (802.11b) card. This module is a WirelessHost less the PPP and Ethernet interfaces, plus mobility support (BasicMobility). It is intended mainly for mobile ad-hoc networks.

WirelessHost2

Models a host with zero, one or more wireless (802.11b) cards. This module is a variation of WirelessHost.

Router

IP router.

WirelessHost

Models a host with one wireless (802.11b) card. This module is basically a StandardHost with a Nic80211 added.

BurstHost

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

OSPFRouter

IP router.

TCPSpoofingHost

IP host with TCPSpoof in the application layer.

LDP_LSR

An LDP-capable router.

RSVP_LSR

An RSVP-TE capable router.

Parameters:

Name Type Description
routerId string

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

turns IP forwarding on/off

routingFile string

routing table file name
