Hi Chris, I think the general view was that RH0, can be deprecated and a new more secure Routing Header can be used to get the functionality for required.
I have put a draft for the checks required, in any such header. I intend to modify the draft to take care of introducing the new Routing Header. It would be great to hear of use cases from the operators where the functionality is required. Thanks, Vishwas On 7/5/07, Christopher Morrow <[EMAIL PROTECTED]> wrote:

I fear that deprecating a part of the spec is going to lead to some confusion (as is shown above) and probably isn't the only option... I had wanted to send some longer feedback to jabley/ipv6@ but missed out it seems :( In short, I think that deprecation removes some functionality that people may want to use (perhaps even for a good reason). There are other issues with removing this from the spec, like making another set of corner cases implementors will have to check for, ala cisco's 'protocols' bug of 2 years ago (just picking an example not picking on a vendor). Giving the network the option to ignore RH0 headers would have skipped us past this problem, and left the spec in good standing for the cases that might want to use it for good. -Chris
