how does a node

is that DAG
It knows it's a left node because it knows that it failed to find
a
compatible OFy.
Why is this a discriminator?
The node could have other child nodes already attached to itself
prior to the node attaching onto the DAG. This set of nodes could
all ascribe to the same OFy, yet be different that the OFx of the main
DAG.
When it's a leaf node, it does not process the DIOs that it receives,
and does not forward that information (list of prefixes, etc.) to it's
parent.
Ok. I assumed that
to eliminate newly found children the node would stop sending DIOs. However,
I wasn't sure if DIOs are needed to be sent out periodically for other
reasons.
