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.
