...                 This suite tests simple connection between one ibgp peer (exabgp) and Odl.
...                 Peer is configured with ipv6, and exabgp connectes to odl via ipv6.
...                 Exabgp sends one ipv6 unicast route, which presence is verified in
...                 example-ipv6-topology. Tests this connection multiple times, with
...                 different ipv6 accepted formats, e.g. (::1, 0:0:0:0:0:0:0:1, full text)
...                 This suite also tests a combination of afi-safis on odl and exabgp.
...                 ipv6 route injection is carried out from odl to the ibgp peer without
...                 ipv6 family enabled on the peer device and checked for exceptions
