Advertising A Host Route; Tuning And Optimizing Ospf Networks; Configuration Prerequisites - HP 6125XLG Configuration Manual

Configuring default parameters for redistributed routes
Perform this task to configure default parameters for redistributed routes, including cost, tag, and type.
Tags indicate information about protocols. For example, when redistributing BGP routes, OSPF uses tags
to identify AS IDs.
To configure the default parameters for redistributed routes:
Step
1. Enter system view.
2. Enter OSPF view.
3. Configure the default
parameters for
redistributed routes (cost,
upper limit, tag, and
type).

Advertising a host route

Step
1. Enter system view.
2. Enter OSPF view.
3. Enter area view.
4. Advertise a host route.

Tuning and optimizing OSPF networks

You can use one of the following methods to optimize an OSPF network:
Change OSPF packet timers to adjust the convergence speed and network load. On low-speed
•
links, consider the delay time for sending LSAs.
• Change the SPF calculation interval to reduce resource consumption caused by frequent network
changes.
Configure OSPF authentication to improve security.
•

Configuration prerequisites

Before you configure OSPF network optimization, complete the following tasks:
• Configure IP addresses for interfaces to ensure IP connectivity between neighboring nodes.
Enable OSPF.
