Added to Zebra as it's rather close to it, and radvd would be a new package.

For router functionality (ie. autoconfiguration) in IPv6, route advertising is required.

IPv6 support has been merged in the initscripts, so I see no problem in adding IPv6 router
support either, first in powertools, later in the main distribution.

Lars Fenneberg has created radvd for this:

I've taken the RPM, and enhanced and Red Hat'ified it:

The changelog:
- use %{_mandir} and friends
- add more flesh to %doc
- streamline %config file %attrs
- streamline init.d file a bit:
   * add a default chkconfig: (default to disable for security etc. reasons; 
     also, the default config isn't generic enough..)
   * add reload/condrestart
   * minor tweaks
   * missing: localization support (initscripts-5.60)
- use %initdir macro
