Pascal,

During the WG meeting yesterday, we discussed using DSCP bits as a way to
identify join request/reply messages. We talked about mapping, in the
minimal-security spec, the different DSCP values to scheduling behavior.

But you indicated the DSCP bits would be in the inside IPv6 header. That
doesn't make sense to me, can you please provide more info? The outside
IPv6 header looks to me like the right place to put the bits.

Thomas
