multihop bgp means that you don't have synchronised ethernet carrier
status between the provider and customer routers.  This in turn means
that if there's an intermediate connectivity problem, bgp will need to
time out before it notices and reroutes.  During this period, traffic
will be black-holed.  This is a crock.
