I see RH0 as a very useful feature for troubleshooting in a network, but I really can't see why a non-routing system should every need or want it. It looks to me like it should be non-existent when routing is not enabled and off by default when it is enabled. That said, in these days of MPLS and wide-area VLANs, the usefulness of this option is far less than it was in the earlier days of the net and I can't remember the last time I used the loose-source route capability of IPv4. I have never used it in IPv6. If it does live on (in any form), it is important that IPFW2 be able to filter it properly (ala Bjoren's patches) so it can be limited to desired connections, typically internal connections. -- R.
