Section 4.2 of: 'draft-templin-ipvlx-02.txt' proposes a link adaptation method for tunnels that uses a probing strategy similar to what is described in 'draft-ietf-pmtud-method-04.txt' and also observes most of the tunnel MTU/MRU determination rules specified in section 3 of 'draft-ietf-v6ops-mech-v2-07.txt'. The proposal supports GbE jumbo frame MTUs on a per-decapsulator basis and also allows host-based segmentation for sending the larger packets when the decapsulator can accept jumbo frames but some L2 switch on the path cannot. This is being mentioned for the sake of providing completeness to this discussion, since it addresses the case of tunnels being used instead of native IPv6 in some deployment scenarios. Although I cannot give a schedule, the document is due for an update after the I-D repository re-opens following IETF63.
