By default, SNMP notifications
for OSPF is enabled.
4. Enter OSPF view.
ospf [ process-id | router-id router-id |

N/A
5. Configure the maximum
number of output SNMP
notifications within a
specified time interval.
snmp trap rate-limit interval trap-interval
count trap-number
By default, OSPF outputs up to
seven SNMP notifications
within 10 seconds.

Configuring the LSU transmit rate
Sending large numbers of LSU packets affects router performance and consumes too much network
bandwidth. You can configure the router to send LSU packets at a proper interval and limit the maximum
number of LSU packets sent out of an OSPF interface each time.
To configure the LSU transmit rate:
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 LSU
transmit rate.
transmit-pacing interval interval count count
By default, an OSPF interface
sends a maximum of three LSU
packets every 20 milliseconds.

Enabling OSPF ISPF
When the topology changes, Incremental Shortest Path First (ISPF) computes only the affected part of the
SPT, instead of the entire SPT.
To enable OSPF ISPF:
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 ] *
