Robert,

I'm having a hard time understanding exactly how I have violated the longest match principle. Could you provide:


  *   A pointer to a statement of the longest match principle
  *   A few words regarding how I have violated it

                                                              Ron

Subject: IPv6 Addresses and SIDs

Hi Ron,

I disagree.

Your suggestion violates longest prefix match principle in routing.

It is huge waist of address space and is not specific to IPv6 at all.

Let me describe the deployment case where your suggestion would cause it to break:

I have /64 prefix where a few  /128s from that space I allocate to local interfaces making it a local v6 destinations on those nodes.

However in the spirit of CIDR I still want to to use some blocks of that space - say  /126 or /124 as blocks which I only use to trigger local NAT as per rfc6296. And NAT does not require local address to be a destination address so it would be a big disservice to kill such deployment option.

Many thx,
R.

Folks,

I think that we need a global rule that says:

"With a /64, if one /128 represents an IPv6 interface, as described in RFC 4291, all /128 MUST either:


  *   Represent an IPv6 interface, as described in RFC 4291, or
  *   Be unassigned"

The 6man WG will need to make such a statement since it owns RFC 4291.

                                                             Ron
