== List of click files: ==
Core MF router - MF_Router_GNRS.click[[BR]]
Virtual Core MF router - MF_VirtualRouter_GNRS.click[[BR]]
Edge MF router - MF_IPAccessMultiRouter.click[[BR]]
Virtual Edge MF router - MF_AccessVirtualRouter_GNRS.click[[BR]]

=== List of Parameters used to configure click elements ===
my_GUID - true GUID of the router  [[BR]]
my_virtual_GUID - GUID for the virtual router instance in the case of a single VN scenario [[BR]]
my_virtual_network_GUID - GUID for the virtual network in the case of a single VN scenario [[BR]]
topo_file - GUID-based topology file  [[BR]]
virtual_topo_file - Virtual GUID-based topology file [[BR]]
virtual_config_file - Mappings between the true and virtual GUIDs of memebers of the VN in single VN scenario [[BR]]
virtual_service_file - Mappings between Service GUID and server GUIDs (instead of GNRS functionality) [[BR]]
core_dev [[BR]]
GNRS_server_port - listening port on server, assumes localhost gnrs [[BR]]
GNRS_listen_ip - IP assoc w/ interface GNRS listens on [[BR]]
GNRS_listen_port - response listening port for gnrs clients [[BR]]
edge_dev - name of wireless interface on which client connects [[BR]]
edge_dev_ip - IP of edge device on this bridge that the client connects on [[BR]]
