Note:
With this command configured, when network changes are not frequent, LSAs are
generated at the
minimum-interval
. If network changes become frequent, LSA
generation interval is incremented by
incremental-interval
•2
n-2
(n is the number of
generation times) each time a generation occurs, up to the
maximum-interval
.

Note:
z
Different OSPF processes can disable the same interface from sending OSPF
packets. Use of the
silent-interface
command disables only the interfaces
associated with the current process rather than interfaces associated with other
processes.
z
After an OSPF interface is set to silent, other interfaces on the router can still
advertise direct routes of the interface in Router LSAs, but no OSPF packet can be
advertised for the interface to find a neighbor. This configuration can enhance
adaptability of OSPF networking and reduce resource consumption.
3.7.8 Configuring Stub Routers
A stub router is used for traffic control. It tells other OSPF routers not to use it to forward
data, but they can have a route to it.
The Router LSAs from the stub router may contain different link type values. A value of
3 means a link to the stub network, so the cost of the link remains unchanged. A value
of 1, 2 or 4 means a point-to-point link, a link to a transit network or a virtual link. In such
cases, a maximum cost value of 65535 is used. Thus, other neighbors find the links to
