    Ignore IPv6 routing cache on linux · 73d8f662
    Baptiste Jonglez authored
    Recent linux kernels (roughly 3.x) keep a routing cache for IPv6: each
    time a host is contacted, a temporary /128 route is added. These
    routes are visible using “ip -6 route show cache”.
    Asking babeld to redistribute all IPv6 routes known to the host, using
    "redistribute ip ::/0", causes it to announce and de-announce these
    /128 routes frequently, leading other nodes to mark them as
    unreachable (thus preventing communication with the host described by
    the /128 route, even though less specific routes are available).
