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•2n-2 (n is the number of generation times) each time a generation occurs, up to
the maximum-interval.
Disabling Interfaces from Sending OSPF Packets
Follow these steps to disable interfaces from sending routing information:
To do...
Enter system view
Enter OSPF view
Disable interfaces from
sending OSPF packets
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.
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.
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 the stub router have such big costs, they will not send packets to
the stub router for forwarding as long as there is a route with a smaller cost.
Use the command...

ospf [ process-id | router-id
router-id | vpn-instance
instance-name ] *
silent-interface { all |
