Re: [Lsr] Working Group Adoption Poll for "OSPF Extension for Prefix Originator" - draft-wang-lsr-ospf-prefix-originator-ext-01

2019-02-28 Thread Acee Lindem (acee)
The adoption call has completed and there is sufficient support for adoption. 
There was some skepticism regarding the limitations on the non-normative 
topology discovery. However, I believe these can be worked out.

Please republish the draft as draft-ietf-lsr-ospf-prefix-originator-00.txt.

Hi, Tony:
Not got well all your comments :(
Wish the explanation in previous mail to Les can change your impression to this

2019-02-21 Thread Aijun Wang
Hi, Les:

The method to retrieve the topology information for inter-area scenario that 
described in the current draft is more easily deployment and less requirements 
for the connections between the controller and underlying routers.
The ELC, ERLD and MSD are capabilities of the routers and can be flooded via 
the mechanisms described in RFC7770. If there is no draft described the details 
process, we can cooperate to write one.

Acee has pointed out that these OSPF areas are often under one administrative 
scope, and they know the address allocation philosophy of their underlying 
networks, then can assure the reliability of the retrieved topology.

Anyway, the aim of this draft is to let reader know how to use the introduced 
extension, not merely the extension itself. 

Best Regards

2019-02-21 Thread Tony Przygienda
I read it during some mildly boring phone conference here ;-) I do
(unsuprisingly) tend to agree with Mr. Ginsberg here. Putting originator on
prefix, well, ok, I understand how people got there instead of having a
clean router LSA with its loopback hanging of it (which would be IMO the
right abstraction but alas, IP decided originally that interfaces have
addresses and routers, well, don't. Overall not the best architecture
remedied by loopback hacks since forever then. I digress ...). So putting
router-id on type-3 loopback serves its purpose of "how do I get to this
node across topology abstractions [areas]". Allows central entities
(controllers and such) to get to every node in the topology without
violating abstractions (too much ;-). Cleaner solutions would be thinkable
but more complex obviously. But coming back to this draft, alas, trying to
build the whole topology distribution tails-up, i.e. redistribute topology
view behind prefixes which are really leafs-of-topology strikes me just
another confused slippery slope just like re-encoding one protocol's native
formats into another protocol :-P ... And if the authors suffer from mild
bout of over-creativity I suggest to split that part into an informational
draft ...

2019-02-21 Thread Les Ginsberg (ginsberg)
Aijun –

Controllers already have a reliable way to learn topology information for all 
areas.
There is therefore no need for the topology discovery solution you propose – 
and all the more so because your proposal does not work in all cases and you 
have no definition of how a controller could tell when the information can be 
trusted and when it can’t.

The only thing which is needed is to define a way to identify the source 
router-id of prefixes which are leaked between areas – which is what I have 
asked you to limit the draft to do.

The mention of ELC/ERLD/MSD in your draft is spurious since you actually 
haven’t defined any way to advertise that information between areas (nor do I 
want you to do so).  It should be removed.

I say again, this draft in its current form is not ready to be adopted.

Thanks for your review and comments.
The use cases and original thought in this draft are different from that

Can’t topology discovery be done using RFC 7770?

2019-02-18 Thread Goethals, Dirk (Nokia - BE/Antwerp)
I think we are in sync, i.e.
without this draft there is no use-case for node T1 to send an
AS-scoped router info LSA without being ASBR.
Please correct if you know of an existing use-case.
Thx,
Dirk

yes, that is a possibility.

I would not think so.

if the T1 advertises some properties in it's AS-scoped LSA and you use

you only care about its properties.





I guess it was needed before as to enforce  the ABR to create the T4

Re: [Lsr] Working Group Adoption Poll for "OSPF Extension for Prefix Originator" - draft-wang-lsr-ospf-prefix-originator-ext-01

2019-02-18 Thread Les Ginsberg (ginsberg)
To the extent that the draft defines functionality equivalent to that defined 
in IS-IS RFC 7794 – specifically a means to advertise the source router-id of a 
given advertisement – it defines a necessary and useful extension to the OSPF 
protocol – and I support that work.

However, in its current form the draft discusses use of this mechanism for 
inter-area topology discovery. This idea is seriously flawed – as has been 
discussed extensively on the WG list.
The draft also discusses uses cases related to ERLD, the direction for which is 
very much uncertain at this time.

I therefore feel that the current content of the draft is not what I would 
expect to see approved by the WG as an RFC and therefore have significant 
reservations about moving forward with the existing content.

I do want to see a draft addressing the source router-id advertisement gap move 
forward – and if this draft is reduced to focus on that then I can 
enthusiastically support adoption – but in its current form I cannot indicate 
support.

1 question:


When S1 in another area receives such LSA, it then can learn that
   prefix Lt1 is associated with node T1, check the ELC, ERLD, or MSD
   value according to its necessity, and construct the right label stack
   at the ingress node S1 for the traffic destined to Lt1.


How is S1 going to know the "ELC, ERLD, or MSD" of  node T1?
I guess, T1 will need to send an AS-scoped router info LSA?


yes, that is a possibility.



If so, should T1 be ASBR as to be able to send this AS-scoped LSA?


I would not think so.



I guess it was needed before as to enforce  the ABR to create the T4 LSAs,
so that others can learn which ABR to use to reach T4, but I guess
it's not needed anymore when this draft is implemented.


not sure how you reached the above conclusion. Can you please clarify?

thanks,
Peter

Dirk

Support as coauthor, although I never really agreed with the usage of 
the prefix originator for topology construction as described  in section 
3 and 5. I would prefer that part to be removed.


thanks,
Peter
