Raj,
When i have configured OSPF i have never made this un-interesting . I
have seen this too, but what i think is if we make it uninteresting then
how will the updates traverse the link whenever there is changes that
need to go thru. OSPF demand ckt is to ensure the hellos and other
keepalive packets dont bring the demand ckt up.
Also when we do configure demand ckt the "Hellos suppressed" should be
seen with the interface.
Good Luck,[IMAGE]
Kasturi.
