-Documentation The objective of this testsuite is to test QBGP and ODL for multipath/ECMP support.
-... QBGP should be capable to receive multiple ECMP paths from different DC-GWs and
-... to export the ECMP paths to ODL instead of best path selection.
-... ODL should be capable to receive ECMP paths and it should program the FIB with ECMP paths.
