Re: [Lsr] Working Group Last Call for "OSPF Link Traffic Engineering (TE) Attribute Reuse" - draft-ietf-ospf-te-link-attr-reuse-07.txt

Hi Oliver,

There are two major purposes served by the drafts:

1)Support of incongruent topologies for different applications

2)Advertisement of application specific values even on links that are in
use by multiple applications

These issues are clearly articulated in the Introductions of both
drafts. LSR WG acknowledged them a while back and decided to address
them.

Issue #1 has already had a significant impact on early deployments of
SRTE in networks where there is partial deployment of SR in the presence
of RSVP-TE.

Issue #2 will be seen in deployments where Flex-Algo and SRTE (or
RSVP-TE) are also present. Early implementers of Flex-Algo can attest to
this.

It is simply not possible to address these issues with the existing
single set of application independent advertisements.

The solutions we provide in both drafts allow to share the link
attributes between application as well as keep them separate if that is
what is required.

thanks,
Peter
