Re: TE/CT Configuration scalability


The other possibility is for someone to propose a "standard" mapping. For
anti-trust reasons, I don't believe that this would be best coming from a
non-carrier. For IETF reasons, I believe that this would be best if it
was proposed as "one possible" mapping, not _THE DEFINITIVE SINGULAR_ mapping.

Section 5.1.7, this references section 4.1, of

Section 7.11

For interarea - I don't see a problem, as it's one administrative domain.

For interas - there may need to be use of diff-serv mpls signalling, or
"careful" coordination between domains.

draft-ietf-tewg-diff-te-proto-07, "Protocol extensions for support of
Differentiated-Service-aware MPLS Traffic Engineering" states:-

"To ensure coherent DS-TE operation, the network administrator MUST
configure exactly the same TE-Class Mapping on all LSRs of the DS-TE
domain"

How does this idea of identical TE/CT configuration work over multiple
domains? Is there any possibility of interoperability?
