Ah, I see. Well, for compatibility with the Babel SADR extension, it
would be good if at least the nest support could be done via separate
data structures (Ondrej's suggestion of a separate address family is not
a bad one). The Babel protocol specifies an extension TLV for SADR
routes that can co-exist with non-SADR routes in the same network. Would
need to support that in Bird as well, so please take that into account
when you modify the Bird core :)
