All,

Attached is a short presentation for the next IETF that summarizes the 
three options for LFB-level multicast:
- merged (among the current proposal in the draft),
- split (among the current proposals in the draft, called VPN, and 
Zsolt's proposal),
-  xcat (Weiming's proposal).

Also, there is a slide with the issue Jamal raised about unnecessarily 
repeating the class ID for commands destined to LFBs of the same class. 
Personally, I think the overhead is minimal. Maybe your view is different ?

Please review the slides and let me know if you have comments/suggestions.

Depending on the chosen solution(s), we may have to define a TLV for the 
LFB Instance ID, as this can be a normal ID, a virtual ID (MIID), a 
list, or a range.
