RFC 5087, "Time Division Multiplexing over IP (TDMoIP)", December 2007

Section 9 says:

   For MPLS PSNs, PW Types for TDMoIP PWs are allocated in [RFC4446].

It should say:

   For MPLS PSNs, PW Types for TDMoIP PWs have originally been allocated
   provisionally in [RFC4446]; IANA has updated the References for MPLS
   pseudowire types 0x0016 and 0x0018 (for TDMoIP AAL1 mode and TDMoIP
   AAL2 mode respectively) in the "pwe3-parameters" registry to point
   to RFC 5087.

   IANA has allocated two pseudowire type values for these encapsulations
   from the "L2TPv3 Pseudowire Types" sub-registry of the "l2tp-parameters"
   registry as follows:
         <TBD1>  -  TDMoIP AAL1 Mode             [RFC5087]
         <TBD2>  -  TDMoIP AAL2 Mode             [RFC5087]

Notes:

The IANA considerations given are incomplete and much too imprecise.

The net result is that IANA has *not* reparented the assignments
for TDMoIP to RFC 5087, leaving the registry inconsistent and
confusing for all but the real PWE3 gurus.

And it has been missed entirely to request allocation of L2TPv3
PW types for the two encapsulations described in RFC 5087.

The NEW text shows what IANA better should have been advised to do
during the publication process of RFC 5087.

Perhaps, it is not too late to have these allocations be performed
after the publication of RFC 5087.
--VERIFIER NOTES--
The PW types registry has been updated so that types 0x16 and 0x18 now point to RFC5087. There seems to be limited value to the reader of RFC5087 in directing them to an erratum describing this registry update.

RFC5611 is the document that describes the signalling for TDM PWs using L2TPv3 and allocation of associated code points.
