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
Optional.
By default, an OSPF interface
sends up to three LSU packets
every 20 milliseconds.
Enabling OSPF ISPF
When a network topology is changed, Incremental Shortest Path First (ISPF) allows the system to
recomputes only the affected part of the shortest path tree (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 ] * N/A
3. Enable OSPF ISPF. ispf enable
Optional.
Disabled by default.
Configuring BFD for OSPF
OSPF supports the following BFD detection methods:
• Control packet bidirectional detection, which requires BFD configuration to be made on both OSPF
routers on the link.
• Echo packet single-hop detection, which requires BFD configuration to be made on one OSPF router
on the link.
Configuring control packet bidirectional detection
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable an OSPF process and enter OSPF
view. ospf [ process-id | router-id router-id |

N/A
3. Specify a network to enable OSPF on the
interface attached to the network.
