  10 ...               This suite tests advertising and receiveing routes with l3vpn content.
  11 ...               It uses odl and exabgp as bgp peers. Routes advertized from odl
  12 ...               are configured via application peer. Routes advertised from exabgp is
  13 ...               statically configured in exabgp config file.
  14 ...
  15 ...               For fluorine and further, instead of exabgp, play.py is used. When sending
  16 ...               routes from odl to peer, first route containg route-target argument have to
  17 ...               be send from peer to odl, so odl can identify this peer. Than it sends l3vpn
  18 ...               route containg this argument to odl app peer, and we check that app peer
  19 ...               advertizes this route back to the peer.
