IDR WG,

I support the WG adoption with the following questions:

  *   How does the BGP speaker know all the target nodes? Is it via configuration?
  *   Does the Node Target Extended Communities message include all the Target identifiers? Suppose one message is for 100 BGP nodes. Does the message need to include all the identifiers of the 100 nodes?
  *   Will you consider adding the “Exclude target” option for a situation where only a small set of nodes is not TARGET?


Inserted below are my answers to the questions:

Cheers,
Linda Dunbar

Subject: draft-dong-idr-node-target-ext-comm-05.txt - WG Adoption and IPR call (9/27 to 10/11/2022)

This begins a 2 week WG adoption and IPR call for draft-dong-idr-node-target-ext-comm-05.txt.
https://datatracker.ietf.org/doc/draft-dong-idr-node-target-ext-comm/<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdatatracker.ietf.org%2Fdoc%2Fdraft-dong-idr-node-target-ext-comm%2F&data=05%7C01%7Clinda.dunbar%40futurewei.com%7C3d95b74570e64d649fe208daab7c14a7%7C0fee8ff2a3b240189c753a1d5591fedc%7C1%7C0%7C638010846671415327%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=mhgvsvk6L4qNMhjU697kIoWko7BkN5z8FwGsTEJa%2ByE%3D&reserved=0>

The authors should respond to this email with an IPR statement.

The WG should consider in their discussion:
1) Will this new  transitive extended community help
in operational networks?

[Linda]  Yes.

2) What conflicts does this new Extended Community have
with other functions in general BGP route distribution or
VPNs (EVPN, IPVPN)?

[Linda] No

3) do you have any concern about the text in the draft?

[Linda] see the questions I have about the draft above.

Cheerily, Sue
