If you are using VPLS then you need to send 1Gbs of broadcast traffic
and see how that cripples your network and send 1Gbps of BPDUs and ARP
requests/responses etc. to see how that ruins everything, as your
customer will loop it at some point. Also to check how your PEs work
and if storm-control or similar is working.
We had an issue with a VPLS instance where different model edge PEs
had their core facing interfaces built in different ways; some had a
physical interface configured facing the core, some a sub-interface,
some an SVI/BVI/BDI etc, it turned out that device X won't tunnel PPP
packets over VPLS/pseudowires when the core facing interface is an
SVI, model Y will but not when using EVCs etc.
People usually test TCP/UDP over IPv4 which doesn't tell you much
about what your equipment/service can or can't do and how it will
