Tom,

We are saying that topology reduction is very effective. In fact, the
load of the full LSAs is much larger than the load due to
synchronization, as seen with all the simulations published so far.

With the MPR topology reduction, up to 50% of the load due to LSAs can
be avoided. It is difficult to match that with adjacency reduction on
its own. However, adjacency reduction can indeed be complimentary, and 
this is also possible with MPR-OSPF, as described in the draft (instead 
of bringing up adjacencies with all its wireless neighbors a wireless
router MAY bring up adjacencies with some of them), while still being
OSPF compliant in the sense that routing is done over adjacencies only.

Emmanuel
