The general topology that most of the tests use is as follows, but each test defines details of the topology based on its needs, and some tests actually use a somewhat different topology. +---------------------+ +---------------------+ | H1 | | H2 | | + $h1 | | $h2 + | +-----|---------------+ +---------------|-----+ | | +-----|------------------------------------------------------|-----+ | SW o---> mirror | | | +---|------------------------------------------------------|---+ | | | + $swp1 BR $swp2 + | | | +--------------------------------------------------------------+ | | | | + $swp3 + gt6 (ip6gretap) + gt4 (gretap) | +-----|----------------:--------------------:----------------------+ | : : +-----|----------------:--------------------:----------------------+ | + $h3 + h3-gt6(ip6gretap) + h3-gt4 (gretap) | | H3 | +------------------------------------------------------------------+ The following axes of configuration space are tested: - ingress and egress mirroring - mirroring triggered by matchall and flower - mirroring to ipgretap and ip6gretap - remote tunnel reachable directly or through a next-hop route - skip_sw as well as skip_hw configurations Apart from basic tests with the above mentioned features, the following tests are included: - handling of changes to neighbors pertinent to routing decisions in mirrored underlay - handling of configuration changes at the mirrored-to tunnel (endpoint addresses, upness) A suite of mlxsw-specific tests will be part of a separate submission through linux-mlxsw patch queue. ==================== Signed-off-by: David S.
