Gyan – Your comments are lengthy – I will start with some general explanation. I believe that you are confused about the hierarchy between PDUs types and scopes. If that were more clear to you, I believe many of your comments would no longer need to be made. PDUs are a container for sending pr

Hi Les & Peter Thank you for the offer to join the Event Notification draft. I agree the Event Notification draft is an innovative solution to the problem statement presented by PUA using a new pulse PDU. I read through the draft and even though it’s a major IGP change to add event notification,

Hi Linda, Thank you for your contribution. I have several comments: 1) I think you could abstract this out from 5G and have a much stronger contribution. If I understand correctly, your goal is to route to optimal instances of anycast load balancers. There’s nothing radio specific about that.

Hey Tom, If you can't get this fixed, you know there are alternative Email services that you could use for IETF work. We're not going to change the protocol name... I'll make it a point to use "IS-IS" (with the hyphen) since that should be easier to get removed from your ESP's filters. Thanks,
