I've submitted a request through my Brocade SE to support this, but it seems they are not interested about it.

They claim their strategy is to achieve the same using SDN capabilities via OPENFLOW support.

In the mean time, we are sitting ducks with our traditional technics.

I read in an old NANOG thread (IIRC) that cisco was about to support this really soon on IOS-XR, but I am not 100% sur.

Best regards.
