Hi eric, hannes,

Just to clarify, ospf is being used in current PE-CE deployment and it is not rare.
My personal experience, for instance, CELCOM from Malaysia and KPN from Netherland are using ospf in their networks.

Regards
Eric

+1

it would be furthermore interesting to hear from the authors how
OSPF behaves once a massive scale of flow-routes 
(lets say in the order of > 100K is injected into OSPF).

| Document date:	2014-09-27
| Group:		Individual Submission
| Pages:		11
| URL:            http://www.ietf.org/internet-drafts/draft-liang-ospf-flowspec-extensions-01.txt
| Status:         https://datatracker.ietf.org/doc/draft-liang-ospf-flowspec-extensions/

| 
| Abstract:
|    This document discusses the use cases why OSPF (Open Shortest Path
|    First) distributing flow specification (FlowSpec) routes is
|    necessary.  This document also defines a new OSPF FlowSpec Opaque
|    Link State Advertisement (LSA) encoding format that can be used to
|    distribute FlowSpec routes.
| 
|    For the network only deploying IGP (Interior Gateway Protocol) (e.g.
|    OSPF), it is expected to extend IGP to distribute FlowSpec routes.
|    One advantage is to mitigate the impacts of Denial-of-Service (DoS)
|    attacks.
| 
| 
|                                                                                   
| 
| 
| Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
