to PF_ROUTE) from NRL's IPv6 distribution, heavily modified by me for better source layout, formatting, and textual conventions. I am told that this code is no longer under active development, but it's a useful hack for those interested in doing work on network security, key management, etc. This code has only been tested twice, so it should be considered highly experimental.
