Hi Folks

General comments include:
1)removing public access recommendation part.
  We can have an informational draft on
  "IPoEo802.16 access in Broadband Network".
2)re-considering distributed bridging funcionalities.
  It is hard to implement when a centralized database needed.

Please check the detailed comments:
1) Section 8
  "Therefore, the AR in the  public access link model
   SHOULD assign common IPv6 prefixes to all SSs
   served by the AR"
  IP addresing is still under discussion in Broadband Forum.
  However, IMO, these is almost a consensus that each
  SS uses a unique IPv6 prefixe.

2)Section 7.3.
 When a network-side bridge receives an ARP request
  from a host behind subsriber-side bridge, the network
  side bridge should discard the request if the destination
  host is also behind the same subscriber-side switch.

3)Appendix B.
  I propose that the edge network-side switchs
  are responsible for host database maitenance, and
  responsing ARP request as a proxy.
  No centralized database is needed.

4)Section 7.2
   It is better to remove TR101 stuff from this section.

BR
Frank
