Name
ip ospf cost — interface
Synopsis
ip ospf costvalue
no ip ospf costvalue
Configures
A default OSPF cost for packets sent out on this interface
Default
108 / bandwidth
Description
This command sets the cost of sending an OSPF packet on an interface to value
. By default, Cisco routers use the bandwidth to determine the link’s cost; high-speed links have a lower cost and are therefore more preferred. Other vendors may have alternative methods for cost calculation. This command can be used as needed to set the cost appropriately in a multivendor environment, or to change the preference of two links of the same type. By default, OSPF
attempts load balancing across links of the same type; this command changes that behavior by modifying the cost associated with each link.
Example
In this example, there are two FDDI links. The second link has a higher cost, causing the router to prefer the first.
