Class StrictBGPPeerRegistry

  • All Implemented Interfaces:
    AutoCloseable, BGPPeerRegistry
    @Singleton
@MetaInfServices
public final class StrictBGPPeerRegistry
extends Object
implements BGPPeerRegistry, AutoCloseable
    BGP peer registry that allows only 1 session per BGP peer. If a second session with peer is established, one of the sessions will be dropped. The session with lower source BGP id will be dropped. This class is thread-safe.
