Default 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.

Graceful 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
transmission of a packet with routing information.
