Detailed Description

template<class A>
class BGPRouteTable< A >

Base class for a stage in BGP's internal plumbing.

The XORP BGP is internally implemented as a set of pipelines. Each pipeline receives routes from a BGP peer, stores them, and applies filters to them to modify the routes. Then the pipelines converge on a single decision process, which decides which route wins amongst possible alternative routes. After decision, the winning routes fanout again along a set of pipelines, again being filtered, before being transmitted to peers.

Each stage in these pipelines is a BGPRouteTable. BGPRouteTable is a virtual base class, so all the stages consist of specialized RouteTable class instances.
