Detailed Description

The XORP BGP is internally implemented as a set of pipelines consisting of a series of BGPRouteTables. 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.

RibInTable is the first stage in such a pipeline. It receives routes from a single BGP peer, and stores them. Changes are passed down the pipeline as they occur, and route lookups from downstream are answered by the RibInTable.
