1.3 Approval of Minutes

Minutes of IAB telecconference on 2007-05-16 were approved.

2. RIPE NCC’s Message about Signing E164.ARPA

It was noted that correspondence had been received from the RIPE NCC regarding the RIPE NCC’s plans to sign the E164.ARPA zone. A was agreed that the IAB would send a courtesy note to the ITU to keep them informed about this recent development. Olaf to draft some text for discussion. RIPE NCC correspondence to be published on the IAB web page.

3. ITU MPLS Liaison

The need for an ongoing MPLS liaison to the ITU was discussed. It was agreed that this liaison role continues to be useful and should be filled.

Consensus was achieved on the choice of MPLS liaison to the ITU. Loa to contact the candidate and confirm that he is still happy to serve.


Loa presented concerns about potential interoperability problems between MPLS as standardised in the IETF, and T-MPLS which is being defined in the ITU, and which appears to use identical code points (e.g. ether-type) to the IETF protocol.

It was agreed that the technical aspects of the problem would be discussed further at IETF 69 in Chicago.

5. Message to ITU-T about BCP 129/RFC 4929

Olaf reported that the Routing Area Directors had requested that the IAB and IESG draw the ITU’s attention to this document, which describes the change process for MPLS and GMPLS protocols and procedures. The usual protocol would be for such a message to be delivered by the ITU-T liaison; however, given the importance of the document it was agreed that having the IAB/IESG send the message would be useful. Olaf to draft text and circulate for comment.

6. IETF 69 Agenda

It was agreed that Loa would present an overview of MPLS during the Sunday afternoon IAB meeting.

7. Enterprise Workshop

The question of whether to pursue an IAB workshop focussed on the needs and concerns of enterprises was discussed. It was agreed that for such an exercise to be of value, a detailed plan for its execution was required, and such a plan would require careful co-ordination. Potential volunteers for this co-ordination role to be discussed on the mailing list.
