routing protocol that bandwidth is statically configured on the link.
The bandwidth value is used by Interior Gateway Routing Protocol (IGRP),
Enhanced Interior Gateway Routing Protocol (EIGRP), and Open Shortest
Path First (OSPF) to determine the metric of the link. This command
also affects bandwidth utilization statistics that can be found by
using the
