Hi PIM,

I've reviewed the latest version and support its progression. The document is a fairly straight forward read extending on the existing P2MP architecture documents and leverages the existing p2mp mpls ping capabilities in an SR way in a clean way.

Authors, some minor text comments/suggestions below.

Thanks
Andrew


Section 3 - it says the ping/traceroute can be initiated from the node that initiates the P2MP Policy. Would it more clear to just say "From the root of the P2MP Policy"?
Section 3.1 - /packet are/packets are/
Section 3.1 /appropriate respond is send/appropriate response is sent/
Section 3.1 "trace route" and others have "Traceroute" - suggest one or the other
Section 3.1 - " On the egress node the corresponding CP and its PI should respond irrespective if it is the active CP or a backup CP."

Seems this statement iis intermixing a few terms that can be misinterpreted depending on the perspective due to the CP, backup CP, and PI active terms. The term "egress" was throwing me off a bit as well. My understanding is the purpose of the text is to indicate the following:

- Every transit and leaf node along the path which has a path instance, those instances are installed, and SHOULD process and respond to ping/traceroute even if that path instance is not active.
- At the root, you may originate a ping/traceroute on the CP even if it is a backup CP. The downstream replication segments installed are independent and follow the previous bullet point.

Therefore would the following text be clearer summary of this?:

"Upon reception of a P2MP Ping/Traceroute, every PI installed on every node SHOULD process and respond to ping/traceroute even if not the active PI"

Hi,

I went through the document and I think it is ready.
It’s an important draft and has implementations, so I support its publication.

Thanks,
Jorge
