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