Blackhole routes in IPv6

Hello,

I have noticed that blackhole static routes are not supported in IPv6, while in IPv4 they are. Do you know why, or whether there is an alternative or not? I need this functionality in BGP, in order to advertise CIDR aggregates.

(For those interested in command line, the functionality I need is the following:

config router static

    edit 1

        set dst <aggregate_network> <aggregate_mask>

        set blackhole enable

    next

end

config router bgp

…

        config network

            edit 1

                set prefix <network> <mask>

            next

        end

end

Thanks

Andreas
