A side note - There is not a total commonality of behaviour/featureset =
between a reflector service at an IXP, and on a single AS. IXP =
route-servers tend to be deployed on pc servers, because the C and J =
units don't have features required[1] for IXP operation (unmodified =
AS-path, filtering between participants, multiple RIBs for shadow-free =
filtering.)
That's not to say that white-box solutions wont work well on your =
network. It's easy to make the reflector highly available too - just =
run multiple reflectors, and build multiple adjacencies on your =
forwarding routers.
