  to 708d4a729dc6a8d0d04006d740964f5eb5cfa72c
  - Local as peer test

    Testing local-as configuration.
    Configures external peer with local-as,
    and internal peer without local-as.

    We connect play.py python tool to both
    peers, and we wait for them to exchange
    routes.

    Local-as from external peer is expected
    on outputs of both peers, and each peer
    should contain the others peer-as.
