Re: [Lsr] LSR Flooding Reduction Drafts - Moving Forward

[Jeff Tantsura <[e-mail]>]

Peter,

As previously stated - I'm against gating, it should be developed in parallel and with cooperation with the ongoing/existing work.
Note - there's a document (albeit expired, it played its role) that talks about generic DC Routing requirements, work in LSR would be scooped to LSR only.
So no going into religious discussions - new vs old/ls vs pv, etc, but focusing on ospf/isis and what is needed for DC specifically.
I think it would be good to do some gain/complexity mental exercise...  

Cheers,
Jeff

    Jeff, All,
    
    we have added many extensions to IGP protocols over the years. Many 
    times multiple solutions were proposed for the same or similar problem 
    and WG picked from the set, many times multiple solutions were merged or 
    combined together. We never asked for a requirement document. Even for 
    more significant changes then we are talking about here.
    
    I understand that the area of DC routing using IGPs is a broader area, 
    but it does not fundamentally change IGPs to warrant the need for 
    requirement document as a prerequisite to move forward with any work 
    that is related to any optimization that may be applicable to DC 
    environment.
    
    So while I'm not against the existence of the document that would cover 
    the requirements for IGPs in DC environments , I don't believe we should 
    gate all proposed work in this space by such a document. And to be 
    completely honest, the requirements are pretty straightforward for 
    anyone that is familiar with the protocols' operation.
    
    my 2c,
    Peter
