# Test-case 1: It requires remote host. Test will setup IPv4 and IPv6 virtual
|
|
# sub-nets between two hosts, then will compare TCP performance
|
|
# with and without VxLAN using ping or netstress test.
|
|
#
|
|
# Test-case 2: The same as above but must fail, because VXLAN allows
|
|
# to communicate only within the same VXLAN segment.
