Configuring The Lsu Transmit Rate; Enabling Ospf Ispf; Configuring Ospf Gr - HP MSR Series Configuration Manual

Step
2. Configure OSPF to give priority
to receiving and processing
hello packets.

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
1. Enter system view.
2. Enter OSPF view.
3. Configure the LSU
transmit rate.

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
1. Enter system view.
2. Enter OSPF view.
3. Enable OSPF ISPF.

Configuring OSPF GR

NOTE:
The device can act as only GR helper.
GR ensures the continuity of packet forwarding when a routing protocol restarts or an active/standby
switchover occurs.
• GR restarter—Graceful restarting router. It must have GR capability.
GR helper—A neighbor of the GR restarter. It helps the GR restarter to complete the GR process.
