Re: DSTM

["JORDI PALET MARTINEZ" <jordi.palet@consulintel.es>]

If we really believe, as a group, that IPv6 is being deployed (and this is actually my personal experience about the market situation), we MUST provide standard mechanism to allow the "backwards transition" stage: when we have some IPv6 only networks and we want to reach IPv4 only networks.

Otherwise it will not make any sense to keep deploying IPv6.

Jordi
