Step 3. Configure the default parameters for redistributed routes (cost, upper limit, tag, and type). Command Remarks Optional. default { cost cost | limit limit | tag tag | type type } * The default cost is 1, the default maximum number of routes redistributed per time is 1000, the default tag is 1, and default type of redistributed routes is Type-2. Advertising a host route Step 1. Enter system view. 2. Enter OSPF view. 3. Enter area view. 4. Advertise a host route. Command system-view ospf [ process-id | router-id router-id | vpn-instance vpn-instance-name ] * area area-id host-advertise ip-address cost Remarks N/A N/A N/A Not advertised by default. 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. Configuration prerequisites Before you configure OSPF network optimization, complete the following tasks: • Configure IP addresses for interfaces. • Configure OSPF basic functions. Configuring OSPF packet timers You can configure the following timers on OSPF interfaces as needed. • Hello timer-Interval for sending hello packets. It must be identical on OSPF neighbors. • Poll timer-Interval for sending hello packets to a neighbor that is down on the NBMA network. The poll interval is at least four times the hello interval. 78
