Re: [Bier] BIER WGLC: draft-ietf-bier-php

Hi Jeffrey,

Thank you for your explanation for comment 3#. It's right. The encapsulation sub-TLV advertisement is optional. I got it. Thank you!
For comment 4, I thought you would like to cover the OSPFv3 extension in this draft. But you are right may it will be a better way to mention the extension in OSPFv3 draft.
Thank you!

Best regards,
Sandy

Hi Greg,

I think this draft is useful in extending BIER deployment.

I do support the progess of this draft.

And I have some comments on this version of draft:

  1.  [I-D.ietf-bier-ospf-bier-extensions] should be replaced by RFC8444.

Zzh> Yes.

  1.  In section 3, the "Label Range Base" should be modified to "Label".

Zzh> Yes.

  1.  With the "Implicit Null Label" advertisement, the associated "BS Len" should be set to 0 to avoid confusion.

Zzh> That is for a particular BSL, so BS Len should not be 0. If one wants a simple signaling for “I don’t support BIER at all but please do PHP”, then it should just use the PHP sub-TLV w/o advertising encap sub-TLV.

4. A nit in section 5, the "OSPFv2" should be "OSPFv3".

Zzh> This is indeed OSPFv2. OSPFv3 signaling draft is newer, so unless this PHP draft is delayed, I’d rather mention PHP in the OSPFv3 draft.

Zzh> Thanks! I will post a revision soon.

Zzh> Jeffrey

Thanks,

Sandy
