Detailed Description

The RedistTable is used to redistribute routes from a routing table back out to a routing protocol. For example, when you want to redistribute BGP routes into OSPF.

For most operations the RedistTable is essentially a passthrough. It keeps track of nets it hears add and deletes for so when route Redistributor objects are added to the RedistTable they can announce the existing routes at startup.

Design note: RedistTable uses a set of IPNet's to cache routes - this should be route entry pointers with an appropriate comparitor (not pointer value based).

typedef set<IPNet<A>,RedistNetCmp<A> > RouteIndex

RouteIndex

 RedistTable (const string& tablename, RouteTable<A>* from_table)

RedistTable

Constructor.

Plumbs RedistTable in RIB graph after from_table.

Parameters:

from_tabletable to redistribute routes from.
 ~RedistTable ()

~RedistTable

Destructor.

Unplumbs table and deletes Redistributor object instances previously added with add_redistributor and not previously removed with remove_redistributor.

void  add_redistributor (Redistributor<A>* r)

add_redistributor

Add a redistributor to announce existing routes and future updates to.

void  remove_redistributor (Redistributor<A>* r)

remove_redistributor

Remove a redistributor.

Redistributor<A>*  redistributor (const string& name)

redistributor

Find redistributor with given name attribute.

int  add_route (const IPRouteEntry<A>& route, RouteTable<A>* caller)

add_route

Reimplemented from RouteTable.
