Petr,
I would like to verify my understanding....To enable ip ospf
flood-reduction, I need to enable "ip ospf demanc-circuit" in all
routers
of the area ?
Copy from the URL you sent :
The main difference between flooding reduction and demand circuits
is that
former suppresses only periodic LSA refreshes; it does not suppress
periodic
hello packets. Thus, the flooding reduction feature does not impair the
detection of a neighbor router going down.
Flooding reduction links have the same constraints as demand
circuits. In
particular, all routers in the area must support the demand circuit
feature
in order for flooding reduction to work. Troubleshooting techniques
for both
demand circuits and flooding reduction links are also common.
This example shows an OSPF flooding reduction feature configuration:
interface POS 0/0
ip address 192.168.122.1 255.255.255.0
*ip ospf flood-reduction*
