Subject: [Roll] Signaling a packet forwarded along a Projected Route

Dear all

To avoid loops it is important that once a packet is placed in a projected route it follows that till destination and does not fall back to the base RPL topology.

The authors are pondering how to make that happen. We see 2 ways:

1) A flag in the RPI but then there can be trouble between a lose storing mode path interconnected with strict non storing hops, since these are all projected DAOs and we would not discriminate.

2) create the projected routes as different instances and allow routing from the base instance into the projected ones.

What do you think?
