  10 ...               This suite tests simple connection between one ibgp peer (exabgp) and Odl.
  11 ...               Peer is configured with ipv6, and exabgp connectes to odl via ipv6.
  12 ...               Exabgp sends one ipv6 unicast route, which presence is verified in
  13 ...               example-ipv6-topology. Tests this connection multiple times, with
  14 ...               different ipv6 accepted formats, e.g. (::1, 0:0:0:0:0:0:0:1, full text)
