This suite uses play.py processes as iBGP rrc peers. ... This is analogue of single peer performance suite, which uses many peers. ... Each peer is of ibgp rrc type, and they contribute to the same example-bgp-rib, ... and thus to the same single example-ipv4-topology. ... The suite looks at example-ipv4-topology and checks BGP peers log for received updates. ... ... ODL distinguishes peers by their IP addresses. ... Currently, this suite requires python utils to be started on ODL System, ... to guarantee IP address block is available for them to bind to. ... ...
