Detailed Description

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.

ResetRouterId()

void ns3::GlobalRouteManager::ResetRouterId ( )

static

Reset the router ID counter to zero.

This should only be called by tests to reset the router ID counter between simulations within the same program. This function should not be called In typical simulations or when using the GlobalRouting helper.
