  10 ...               Test suite performs basic iBGP functional test cases for
  11 ...               BGP peers in different roles (iBGP, iBGP RR-client):
  12 ...
  13 ...               Test Case 1: Two iBGP RR-client peers introduce prefixes
  14 ...               Expected result: controller forwards updates towards both peers
  15 ...
  16 ...               Test Case 2: Two iBGP peers: one RR client and one non-client introduces prefixes
  17 ...               Expected result: controller forwards updates towards both peers
  18 ...
  19 ...               Test Case 3: Two iBGP RR non-client peers introduce prefixes
  20 ...               Expected result: controller does not forward any update towards peers
  21 ...
  22 ...               For polices see: https://wiki.opendaylight.org/view/BGP_LS_PCEP:BGP
  23 ...
  24 ...               Covered bugs:
  25 ...               Bug 4791 - BGPSessionImpl: Failed to send message Update logged even all UPDATE mesages received by iBGP peer
  26 ...               Bug 4819 - No routes advertised to one of newly configured iBGP RR-client peer
