public class ApplicationPeer
extends BGPPeerStateImpl
implements org.opendaylight.mdsal.dom.api.ClusteredDOMDataTreeChangeListener

Application Peer is a special case of BGP peer. It serves as an interface for user to advertise user routes to ODL and through ODL to other BGP peers.

This peer has it's own RIB, where it stores all user routes. This RIB is located in configurational datastore. Routes are added through RESTCONF.

They are then processed as routes from any other peer, through AdjRib, EffectiveRib,LocRib and if they are advertised further, through AdjRibOut.

For purposed of import policies such as Best Path Selection, application peer needs to have a BGP-ID that is configurable.
