Specifying the LSA generation interval
You can adjust the LSA generation interval to protect network resources and routers from being over
consumed by frequent network changes.
When network changes are not frequent, LSAs are generated at the minimum-interval. If network
changes become frequent, the LSA generation interval is incremented by incremental-interval × 2
n-2 (n is
the number of generation times) each time a LSA generation occurs until the maximum-interval is
reached.
To configure the LSA generation interval:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter OSPF view.
ospf [ process-id | router-id router-id |
vpn-instance vpn-instance-name ] *
N/A
3. Configure the LSA
generation interval.
lsa-generation-interval
maximum-interval [ initial-interval
[ incremental-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, but the interface cannot send any packet. This configuration
can enhance OSPF adaptability and reduce resource consumption.
To disable interfaces from receiving and sending routing information:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter OSPF view.
ospf [ process-id | router-id router-id
| vpn-instance vpn-instance-name ] *
N/A
3. Disable interfaces from
receiving and sending
OSPF packets.
silent-interface { interface-type
interface-number | all } Optional.
Enabled by default.
Configuring stub routers
A stub router is used for traffic control. It tells other OSPF routers to not use it to forward data.
The 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
