Support for WG LC. I think this can be a useful building block for TRILL directory service.

Thanks,
Mingui

Subject: [trill] WG LC for draft-ietf-trill-ia-appsubtlv-03 - 2 week WG LC (5/29 to 6/12)

This begins a 2 week WG LC for draft-ietf-trill-ia-appsubtlv-03 (5/29 to 6/12) .  The authors (Donald, Radia, Yizhou) should send a note to the list on whether they know of any IPR relating to this drasft.

You can find the document at:

http://datatracker.ietf.org/doc/draft-ietf-trill-ia-appsubtlv/

This draft specifies a TRILL IS-IS application sub-TLV that enables the reporting by a
   TRILL switch of sets of addresses such that all of the addresses in
   each set designate the same interface (port) and the reporting for
   such a set of the TRILL switch by which it is reachable. For example,
   a 48-bit MAC (Media Access Control) address, IPv4 address, and IPv6
   address can be reported as all corresponding to the same interface
   reachable by a particular TRILL switch. Such information could be
   used in some cases to synthesize responses to or by-pass the need for
   the Address Resolution Protocol (ARP), the IPv6 Neighbor Discovery
   (ND) protocol, or the flooding of unknown MAC addresses.

For this draft, please answer the following questions:


1)      Is this draft ready for WG LC?

2)      Do you think this address passing mechanism will aid deployments of TRILL by

resolving some addressing distribution issues,

3)      Is there any technical issue with this solution?
