    Arsi> For example, configuration of the network is as follows:

    Arsi> - device under test (Linux/Debian, XORP) and five simulated
    Arsi> routers

    Arsi> - AS 1 is advertised to ports eth1 and eth2

    Arsi> - AS 2 is advertised to ports eth1 and eth2

    Arsi> - AS 3 is advertised to port eth3

    Arsi> - Policy rules so that AS 2 routes are not advertised to AS 1

    Arsi> BGP process dies when one of the routers in AS 2 goes down and
    Arsi> then up so that the primary route in AS 2 changes.

    Arsi> Regards, A.A.
