A global global router.
This singleton object can query interface each node in the system for a GlobalRouter interface. For those nodes, it fetches one or more Link State Advertisements and stores them in a local database. Then, it can compute shortest paths on a per-node basis to all routers, and finally configure each of the node's forwarding tables.
The design is guided by OSPFv2 RFC 2328 section 16.1.1 and quagga ospfd.

void ns3::GlobalRouteManager::PopulateRoutingTables | ( | NodeContainer | c | ) | [static] |
Build a routing database and initialize the routing tables of the nodes in the simulation. Makes the nodes in the provided container into routers.
All this function does is call the three functions SelectRouterNodes (), BuildGlobalRoutingDatabase (), and InitializeRoutes ().

void ns3::GlobalRouteManager::RecomputeRoutingTables | ( | ) | [static] |
Remove all routes that were previously installed in a prior call to either PopulateRoutingTables() or RecomputeRoutingTables(), and add a new set of routes.
This method does not change the set of nodes over which GlobalRouting is being used, but it will dynamically update its representation of the global topology before recomputing routes. Users must first call PopulateRoutingTables() and then may subsequently call RecomputeRoutingTables() at any later time in the simulation.
