Configure the default parameters for redistributed routes
You can configure default parameters, such as the cost, upper limit, tag and type for redistributed routes.
Tags indicate information related to protocols. For example, when redistributing BGP routes, OSPF uses
tags to identify AS IDs.
Follow these steps to configure the default parameters for redistributed routes:

tag is 1, and default type
of redistributed routes is
Type-2.

Tuning and optimizing OSPF networks
You can optimize your OSPF network in the following ways:
•
Change OSPF packet timers to adjust the OSPF network 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.
•
Configure OSPF network management functions, such as binding OSPF MIB with a process,
sending trap information, and collecting log information.
