3. Configure the LSA
generation interval.
lsa-generation-interval

Optional.
By default, the maximum interval is 5
seconds, the minimum interval is 0
milliseconds, and the incremental
interval is 5000 milliseconds.
Disabling interfaces from receiving and sending OSPF packets
Follow these guidelines when you disable interfaces from receiving and sending OSPF packets:
• Different OSPF processes can disable the same interface from receiving and sending OSPF packets.
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. However, the silent OSPF interface blocks OSPF packets and
cannot establish any OSPF neighbor relationship, which enhances OSPF adaptability and reduces
resource consumption.
To disable interfaces from receiving and sending routing information:

1. Enter system view.
system-view N/A
2. Enter OSPF view.

3. Disable interfaces from
receiving and sending
OSPF packets.
silent-interface { interface-type
interface-number | all }
Optional.
By default, interfaces receive and
send OSPF packets.
Configuring stub routers
A stub router is used for traffic control. It tells other OSPF routers to not use it to forward data although
they can have a route to it. A stub router has nothing to do with a stub area.
Router LSAs from the stub router might contain different link type values. A value of 3 means a link to a
stub network, and the cost of the link will not be changed. A value of 1, 2 or 4 means a point-to-point link,
a link to a transit network, or a virtual link. On such links, a maximum cost value of 65535 is used.
Neighbors do not send packets to the stub router as long as they have a route with a smaller cost.

2. Enter OSPF view.

3. Configure the router as a
stub router.

By default, the router is not a stub
router in any OSPF process.
Configuring OSPF authentication
Configure OSPF packet authentication to ensure the security of packet exchange.
