Hi Everyone,

    Michael, Steffan, Huaimo and Mike met to discuss the merge and we are in agreement that if draft-chen-bier-frr is adopted we will expand it to include a framework along with the tunnel and LFA based solutions.

Best Regards,
Huaimo

Subject: Re: [Bier] WG adoption call for draft-chen-bier-frr-02

+1

I think it's a good addition within the architecture for the case IGP is not used for signalling, e.g. when controller or static programming.

The draft must however explain in what scenarios it is used and quote the according IGP drafts to guarantee loop-free behavior (well, BIER will tie-break loops but we'll have 1x microloop & possibly not deliver payload if BIER FRR is not properly computed/intsalled). With that the draft should also pay attention to how the function is deployed/updated network-wide if IGP is not present

thanks
