Fwd: I-D ACTION:draft-huitema-shim6-ingress-filtering-00.txt

[marcelo bagnulo braun <marcelo@it.uc3m.es>]

Hi,

We would like to submit the following draft for consideration to the  
working group.

The goal of this document is to provide ingress filtering compatibility  
for multihomed sites, fitting in the charter in the item described as:

   In addition to the network layer shim solution, the shim6 WG is
   specifically chartered to work on:

   o Solutions for site exit router selection that work when each ISP
   uses ingress filtering, i.e. when the chosen site exit needs to
   be related to the source address chosen by the host. This site
   exit router selection and the associated address selection
   process should work whether or not the peer site supports
   the shim6 protocol.

In particular, the approach proposed in the draft provides support for  
legacy hosts (within and outside the the multihomed site) allowing this  
legacy hosts to be able to properly communicate without being affected  
by the availability of multiple prefixes/ISPs in the site, as required  
in RFC 3582:

   The solution should not destroy IPv6 connectivity for a legacy host
   implementing RFC 3513 [4] , RFC 2460 [1] , RFC 3493 [5], and other
   basic IPv6 specifications current in April 2003.  That is to say, if
   a host can work in a single-homed site, it should still be able to
   work in a multihomed site, even if it cannot benefit from site-
   multihoming.

   It would be compatible with this goal for such a host to lose
   connectivity if a site lost connectivity to one transit provider,
   despite the fact that other transit provider connections were still
   operational.

So, we would like to know if the working group would be willing to take  
on this document and continue with this approach.

Regards, marcelo
