Detecting inactive neighbors over demand circuit

[armstrong mathiayalagan <arms at YOURS.COM>]

Hi,
        This draft recommends (May clause) Router LSA to be flooded for Neighbor
probing.
        With respect to the applicability of this draft to OSPFv3, I feel Link LSA
is a good choice for using in neighbor probing than Router LSA.
        In Demand Circuit, there are more chances for having LSAs of different
sequence number at both ends.
        If neighbor probing uses Router LSA, if the Router LSA is having higher
sequence number than the neighbors database, then the neighbor will flood
these LSA in all the non demand circuit interface. This can be avoided by
using Link LSA.
        Comments are welcome.

Regards,
Anu
