[DNA] draft-ietf-dna-frd-00.txt clarification for RA trigger

["Kent Leung (kleung)" <kleung@cisco.com>]

 

Hi folks.  Just joined the alias.  Hope this has not been discussed already.

 

This section says that the PoA can send RS to trigger RA from the AR.  What's not clear is what source link-layer address is put into the TSLLAO option (maybe it's implicit)?  I'm assuming that the source link-layer address of the RS is the PoA, and the address in TSLLAO is the host so the RA can be unicasted directly to the host.

3.1  RA Triggering

   There are two ways for such a remote Link Up event notification.  We
   may use the MIES (Media Independent Event Service) defined in IEEE
   802.21 [21] or RS with TSLLAO (Tentative Source Link-Layer Address
   Option) [14].

In the 802.11 example below, no mention of RS method.  In this case, the AP will send RS with source MAC 

address being AP's and the TSLLAO containing the host.

 
5.2.1  802.11

   In 802.11 Wireless LAN technology, when a new host arrives at an
   AP(Access Point), it should associate with the AP.  The host sends an
   Association Request Message with its MAC address.  Then the AP sends
   an Association Response Message to grant association.

   As soon as association is made, the AP sends a cached RA to the host
   in an unicast 802.11 frame with the MAC address from the Association
   Request message.  The host receives the unicast RA just after
   association is made, which is the earliest possible time in current
   standard.
 
 
What is the status of  draft-daley-ipv6-tsllao-02.txt?  Is this being adopted 
in IPv6 or DNA WG?
 
Thanks for clarifying.
