Global routing protocol for IPv4 stacks.
Introspection did not find any typical Config paths.
In ns-3 we have the concept of a pluggable routing protocol. Routing protocols are added to a list maintained by the Ipv4L3Protocol. Every stack gets one routing protocol for free – the Ipv4StaticRouting routing protocol is added in the constructor of the Ipv4L3Protocol (this is the piece of code that implements the functionality of the IP layer).
As an option to running a dynamic routing protocol, a GlobalRouteManager object has been created to allow users to build routes for all participating nodes. One can think of this object as a "routing oracle"; it has an omniscient view of the topology, and can construct shortest path routes between all pairs of nodes. These routes must be stored somewhere in the node, so therefore this class Ipv4GlobalRouting is used as one of the pluggable routing protocols. It is kept distinct from Ipv4StaticRouting because these routes may be dynamically cleared and rebuilt in the middle of the simulation, while manually entered routes into the Ipv4StaticRouting may need to be kept distinct.
This class deals with Ipv4 unicast routes only.
No TraceSources are defined for this type.
Group: Internet
Size of this type is 144 bytes (on a 64-bit architecture).

Destructor implementation.
This method is called by Dispose() or by the Object's destructor, whichever comes first.
Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.
It is safe to call GetObject() from within this method.
Reimplemented from ns3::Object.

Ipv4RoutingTableEntry * ns3::Ipv4GlobalRouting::GetRoute | ( | uint32_t | i | ) | const |
Get a route from the global unicast routing table.
Externally, the unicast global routing table appears simply as a table with n entries. The one subtlety of note is that if a default route has been set it will appear as the zeroth entry in the table. This means that if you add only a default route, the table will have one entry that can be accessed either by explicitly calling GetDefaultRoute () or by calling GetRoute (0).
Similarly, if the default route has been set, calling RemoveRoute (0) will remove the default route.
i | The index (into the routing table) of the route to retrieve. If the default route has been set, it will occupy index zero. |

Query routing cache for an existing route, for an outbound packet.
This lookup is used by transport protocols. It does not cause any packet to be forwarded, and is synchronous. Can be used for multicast or unicast. The Linux equivalent is ip_route_output()
The header input parameter may have an uninitialized value for the source address, but the destination address should always be properly set by the caller.
p | packet to be routed. Note that this method may modify the packet. Callers may also pass in a null pointer. |
header | input parameter (used to form key to search for the route) |
oif | Output interface Netdevice. May be zero, or may be bound via socket options to a particular output interface. |
