Detailed Description

template<class A>
class RibInTable< A >

Specialized BGPRouteTable that stores routes from a BGP peer.

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.


Member Function Documentation

template<class A >
void RibInTable< A >::flush ( )

Remove all the stored routes.

Used to flush static routes only.

template<class A>
void RibInTable< A >::igp_nexthop_changed ( const A &  bgp_nexthop) [virtual]

Notification that the status of this next hop has changed.

Parameters:
bgp_nexthopThe next hop that has changed.

Reimplemented from BGPRouteTable< A >.
