Hi Sue, All,


Support to progress this draft.

Please be aware that no code point is assigned yet to the Flex Algo Exclude
SRLG TLV (chapter 3.5 of draft BGP-LS Extensions for Flex-Algo).


Nokia has an implementation of this draft.

This begins a 2 week WG LC for  draft-ietf-idr-bgp-ls-flex-algo-04.txt 

(11/1 to 11/16).   


The authors should send their IPR statements by Tuesday (11/3)

or this WG LC will be extended 1 extra week. 


You can access the draft at:


This draft is also needed to match BGP work to LSR specification 

for draft-ietf-lsr-flex-algo-13.txt (at IESG). 


There are 2 Cisco implementations of draft-ietf-idr-bgp-ls-flex-algo. 

Details on the implementations are at:


WG members should consider in their response: 


a) Are there technical issues with the flexible algorithm technology? 

b) Is this draft ready for publication? 

c) Will this technology aid LSR deployments? 

d) Are you concerned about the 2 implementations coming 

only from Cisco? 


If you know of any other planned implementations, please send 

Chairs this information or respond to this email to inform the WG. 


Cheers, Susan Hares
