public class MultiTableMapCache extends Object implements IMapCache
Multi table map-cache that works with 'simple' and SourceDest LCAF addresses (see lisp-proto.yang). It can do longest prefix matching for IP and SourceDest LCAF addresses. In case of the latter, it uses two tables, one for dst and another for source, queried and populated in this exact order.
