Here are some of the additional changes proposed for the P2P draft:

1. Specify minimum life time of the temporary DAG as a 4-bit exponent of 2 (in units of seconds). This will allow the minimum life time to vary between 2^0 to 2^15 seconds.

2. Associate a life time with hop-by-hop state established using P2P mechanism. Or we could let the implementation decide when to clean up the state that has not been used for a while.

3. Allow nodes to ignore routing metrics they dont understand as long as such metrics are not used in propagation constraints. Currently, the P2P draft requires a node to discard the DIO for the temporary DAG if it does not understand a metric contained in the metric container.

4. Require specification of route constraints inside Route Discovery Option. This is done to separate route constraints from propagation constraints (that would be present outside the Route Discovery Option) more cleanly. Currently, the propagation and route constraints are identified based on whether they appear before or after the Route Discovery Option.
