10.2.7Default Metric

OSPF finds metric based on interface bandwidth. For example, default metric of T1 link is 64, but default metric of 64K line is 1562. If there are plural lines in the bandwidth, you can view costs to use line by assigning metric to each line.

To classify costs to use line, use the following command.

Command	Mode	Description
auto-cost reference-bandwidth	Router	Configures default metric in the unit of Mbps.
<1-4294967>		(default: 100)

To delete the configuration, use the following command.

10.2.8Graceful Restart Support

You need to restart OSPF protocol processor when there is network problem. In this case, it takes long time to restarts OSPF and there is no packet transmission. Other routers are also need to delete routing information and register it again. Graceful Restart improves those inconveniences. Although OSPF is restarting, Graceful Restart makes the trans- mission of a packet with routing information.
