Hello authors,

Installing routes by DAO projection in NS-MOP will help in establishing
optimized P2P paths, as well as it will help in containing the 6lo
fragmentation resulting out of bulged SRH at 6LBR.
Thanks for the work.

There are few observations/Qs:
1. The draft discusses about projecting DAO for route installations. But i
assume the same projection mechanism can be used for route removal (?).
This might be needed considering that NPDAO is not required in NS-MOP and
that the VIA lifetimes could be high.
2. Did you also considered installing an SRH (for downstream dest) at
intermediate 6LR rather that installing routes along a segment (segment as
per defn in the draft)?
3. There is a redundant paragraph and missing lines at the end of section 5
which tries explaining the example. Please fix the draft and will be nice
to check that example.

Regards,
Rahul
