Detailed Description
An interface aggregated to a node to provide global routing info.
An interface aggregated to a node that provides global routing information to a global route manager. The presence of the interface indicates that the node is a router. The interface is the mechanism by which the router advertises its connections to neighboring routers. We're basically allowing the route manager to query for link state advertisements.
Member Function Documentation
| uint32_t ns3::GlobalRouter::DiscoverLSAs | ( | void | ) |
Walk the connected channels, discover the adjacent routers and build the associated number of Global Routing Link State Advertisements that this router can export.
This is a fairly expensive operation in that every time it is called the current list of LSAs is built by walking connected point-to-point channels and peeking into adjacent IPV4 stacks to get address information. This is done to allow for limited dynamics of the Global Routing environment. By that we mean that you can discover new link state advertisements after a network topology change by calling DiscoverLSAs and then by reading those advertisements.
- See also:
- GlobalRoutingLSA
- GlobalRouter::GetLSA ()
- Returns:
- The number of Global Routing Link State Advertisements.
| Ipv4RoutingTableEntry* ns3::GlobalRouter::GetInjectedRoute | ( | uint32_t | i | ) |
Return the injected route indexed by i.
- Parameters:
-
i the index of the route
- Returns:
- a pointer to that Ipv4RoutingTableEntry is returned
| bool ns3::GlobalRouter::GetLSA | ( | uint32_t | n, | |
| GlobalRoutingLSA & | lsa | |||
| ) | const |
Get a Global Routing Link State Advertisements that this router has said that it can export.
This is a fairly inexpensive expensive operation in that the hard work was done in GetNumLSAs. We just copy the indicated Global Routing Link State Advertisement into the requested GlobalRoutingLSA object.
You must call GlobalRouter::GetNumLSAs before calling this method in order to discover the adjacent routers and build the advertisements. GetNumLSAs will return the number of LSAs this router advertises. The parameter n (requested LSA number) must be in the range 0 to GetNumLSAs() - 1.
- See also:
- GlobalRoutingLSA
- GlobalRouting::GetNumLSAs ()
- Parameters:
-
n The index number of the LSA you want to read. lsa The GlobalRoutingLSA class to receive the LSA information.
- Returns:
- The number of Global Router Link State Advertisements.
| uint32_t ns3::GlobalRouter::GetNInjectedRoutes | ( | void | ) |
Get the number of injected routes that have been added to the routing table.
- Returns:
- number of injected routes
| uint32_t ns3::GlobalRouter::GetNumLSAs | ( | void | ) | const |
Get the Number of Global Routing Link State Advertisements that this router can export.
To get meaningful information you must have previously called DiscoverLSAs. After you know how many LSAs are present in the router, you may call GetLSA () to retrieve the actual advertisement.
- See also:
- GlobalRouterLSA
- GlobalRouting::DiscoverLSAs ()
- GlobalRouting::GetLSA ()
- Returns:
- The number of Global Routing Link State Advertisements.
| Ipv4Address ns3::GlobalRouter::GetRouterId | ( | void | ) | const |
Get the Router ID associated with this Global Router.
The Router IDs are allocated in the RoutingEnvironment -- one per Router, starting at 0.0.0.1 and incrementing with each instantiation of a router.
- See also:
- RoutingEnvironment::AllocateRouterId ()
- Returns:
- The Router ID associated with the Global Router.
| static TypeId ns3::GlobalRouter::GetTypeId | ( | void | ) | [static] |
The Interface ID of the Global Router interface.
This method returns the TypeId associated to ns3::GlobalRouter.

| void ns3::GlobalRouter::InjectRoute | ( | Ipv4Address | network, | |
| Ipv4Mask | networkMask | |||
| ) |

- Parameters:
-
network The Network to inject networkMask The Network Mask to inject
| void ns3::GlobalRouter::RemoveInjectedRoute | ( | uint32_t | i | ) |
Withdraw a route from the global unicast routing table.
Calling this function will cause all indexed routes numbered above index i to have their index decremented. For instance, it is possible to remove N injected routes by calling RemoveInjectedRoute (0) N times.
- Parameters:
-
i The index (into the injected routing list) of the route to remove.
