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:
Ste
p
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 default
parameters for
redistributed routes (cost,
upper limit, tag, and
type).
default { cost cost | tag tag | type type } *
By default, the cost is 1, the
tag is 1, and the type is
Type-2.

By default, no host route is
advertised.
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.
