FYI -- IPv6 Multi-homing BOF at NANOG 35

[David Meyer]

 	Folks,
 
 	The IAB has proposed the below BOF for the upcoming NANOG
 	(please see http://www.nanog.org for information on
 	NANOG). As mentioned in the description (see below), the
 	purpose of the BOF is for the IAB to solicit operator
 	feedback on the progress and direction of IETF IPv6
 	multi-homing work, and to help the IAB determine if there
 	is meaningful work that it can do (or can signal to the
 	appropriate IETF working group(s)) to address any issues
 	that may be perceived with the current direction.      
 
 	Please let us know if you have any questions or comments,
 	and watch the NANOG pages in the upcoming days for the
 	NANOG agenda. 
 
 	Thanks, and hope to see you there.
 
 	Dave (for the IAB)

 IAB IPv6 Multi-Homing BOF
 
 
 With the advent of the growing and wide-spread deployment of
 IPv6, many familiar operational issues have arisen. Among the
 current IPv6 "hot topics" are RIR policy (including the HD ratio
 discussion) and site multi-homing. This BOF proposal focuses on
 the multi-homing issue, since multi-homing is one of the
 significant drivers of the growth and dynamic properties of
 Default Free Zone (DFZ). In particular, there is concern that
 that the amount of multi-homing will grow beyond the
 organizations who use it today in the IPv4 Internet and that 
 new mechanisms will be required to to handle that growth. 
 
 The current direction that the IETF is taking is being defined by
 the shim6 working group. Briefly, shim6 seeks to find a mechanism
 which provides most the functional benefits of multi-homing while
 still allowing reasonable scalability of the DFZ. Note that 
 multi-homing under shim6 differs from multi-homing under IPv4
 since in IPv4 case, multi-homing is accomplished (in most cases)
 by injecting a provider-independent (PI) prefix into the DFZ.
 This approach has the property that it scales in the number of
 multi-homed sites; each multi-homed site requires an unique entry
 in the DFZ. shim6 differs from the IPv4 approach in that it does
 not require an entry in the DFZ per multi-homed site. 
 
 The purpose of this BOF for the IAB is to solicit operator
 feedback on the progress and direction of IPv6 multi-homing work,
 particularly as discussed in the IETF, and to help the IAB
 determine if there is meaningful work that it can do or can
 signal to the appropriate IETF WGs to address any problem(s) that
 may be perceived with the current direction.   Minimally, notes
 of the session will be posted for those unable to attend the
 discussion in person.
