Alternatively, we could just keep this within our WG and add the following to the 1588oMPLS draft: LSRs that adjust the CF field MAY not update the UDP checksum in case of IPv6. The node that terminates the tunnel MUST recompute the UDP checksum after MPLS decapsulation and before any further processing. This way the 1588aware LSRs only need to update the CF field at the line rate in the HW and need not worry about the correcting/recomputing the UDP checksum. The tunnel terminating node after stripping off the MPLS labels can recompute the UDP checksum and pass it on to the PTP layer above where it will be processed.
