Hi
   
  "ip ospf flood reduction" just avoid the refreshement of LSA every 30 minutes.
   
  "ip ospf demand circuit" mean that a link which is under an OSPF area , don,t send OSPF hello packet all the time. This avoid the fact of bring the circuit (probaly and dial or isdn) just for sent hello packet periodically, the neigbhor relations is still maintaned.

  Hi All,

Can any one tell me , when the commands "ip ospf flood reduction" is used
over " ip ospf demand circuit" .
I know that, "Ip ospf demand circuit is used in point to point connections.
Does that mean, ip ospf flood reduction"
is used in Broadcast and NBMA OSPF networks. I am bit confused as to which
command
to apply in a particular scenario, mainly if the question asks to reduce the
"paranoid updates" in ospf
that occurs every 30mins.

Thanks in advance.

Regards
Shamin
