5000 Series Layer 2/3 Managed Data Center Switch CLI Reference Guide 8-72 auto-cost reference-bandwidth (OSPFv3) The OSPF computes, by default, the link cost of each interface from the interface bandwidth. Faster links will have lower metrics, which makes them better options in route selection. The configuration parameters for the auto-cost reference bandwidth and bandwidth commands give the user control over the default link cost. As such, the user can configure an interface bandwidth for the OSPF that is independent of the actual link speed. Another configuration parameter allows the user to control the ratio of the interface bandwidth to link cost. The link cost itself is calculated as the ratio of a reference bandwidth to the interface bandwidth (ref_bw / interface bandwidth), where the interface bandwidth is determined by the bandwidth command. Due to the default reference bandwidth being 100 Mbps, the OSPF uses the same default link cost for all of the interfaces with a bandwidth of 100 Mbps or greater. The auto-cost command can be used to change the reference bandwidth, with the reference bandwidth being specified in megabits per second (Mbps). The allowed range for the reference bandwidth is 1-4294967 Mbps. The no command sets the reference bandwidth back to the default value. auto-cost reference-bandwidth 1-4294967 no auto-cost reference-bandwidth Parameters None Default The default is 100Mbps. Command Mode Router OSPFv3 Config 8-73 clear ipv6 ospf The clear ipv6 OSPF command is used to clear routing, disables and enable OSPF. clear ipv6 ospf Parameters None Default The default is None. Command Mode Privileged EXEC 860
