# NullLinkProvider topology description (config file).
#
# Dot-style topology graph. Each controller's topology begins with
#
#   graph <node ID>, followed by a list of links between braces.
#
# The links are either bidirectional (--) or directed (->). The directed
# edges are used to connect together Null devices of different controllers.
# The endpoint has the format:
# 
#   devID:port:NodeId
#
# The NodeId is only added if the destination is another node's device.
