Purpose: For informtion


Thank you for your Liaison statement on progress on T-MPLS OAM
definition of March 13th. Due to the very short response period
(17 days), which coincide with the preparations for and the IETF
meeting in Prague it has not been possible for the working groups
to review and respond.

The two documents we received have been brought to the working groups
attention, and the estimate is that it will take us 6 weeks to compile
a consolidated response, however most of this discussion will take
place on the on the mpls and pwe3 working group mailing lists.

We would also like bring your attention to an existing work in
progress relevant to the subject matter in the IETF, and suggest
that this serve as basis for an unified OAM definition for this
area.
