Configuring The Lsu Transmit Rate; Enabling Ospf Ispf; Configuring Ospf Frr - HP 3600 v2 series Configuration Manual

To do...
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.
Follow these steps to configure the LSU transmit rate:
To do...
Enter system view
Enter OSPF view
Configure the LSU
transmit rate

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.
Follow these steps to enable OSPF ISPF:
To do...
Enter system view
Enter OSPF view
Enable OSPF ISPF

Configuring OSPF FRR

NOTE:
Do not use FRR and BFD at the same time. Otherwise, FRR may fail to take effect.
•
Do not use the fast-reroute auto command together with the commands vlink-peer.
•
Introduction
When a link fails, the packets on the link are discarded, and a routing loop may occur until OSPF
completes routing convergence based on the new network topology.
You can enable OSPF fast reroute (FRR) to solve this problem.
