area virtual-link transmit-delay (OSPF)
This command configures the transmit delay for the OSPF virtual interface on the virtual
interface identified by <areaid> and <neighbor>. The <neighbor> parameter is the
Router ID of the neighbor. The range for seconds is 0–3,600 (1 hour).
Default
Format area <areaid> virtual-link <neighbor> transmit-delay <seconds>
Mode
no area virtual-link transmit-delay
This command resets the default transmit delay for the OSPF virtual interface to the default
value.
Format no area <areaid> virtual-link <neighbor> transmit-delay
Mode
auto-cost (OSPF)
By default, OSPF computes the link cost of each interface from the interface bandwidth.
Faster links have lower metrics, making them more attractive in route selection. The
configuration parameters in the auto-cost reference bandwidth and bandwidth
commands give you control over the default link cost. You can configure for OSPF an
interface bandwidth that is independent of the actual link speed. A second configuration
parameter allows you to control the ratio of interface bandwidth to link cost. The link cost is
computed as the ratio of a reference bandwidth to the interface bandwidth (ref_bw / interface
bandwidth), where interface bandwidth is defined by the bandwidth command. Because the
default reference bandwidth is 100 Mbps, OSPF uses the same default link cost for all
interfaces whose bandwidth is 100 Mbps or greater. Use the auto-cost command to
change the reference bandwidth, specifying the reference bandwidth in megabits per second
(Mbps). The reference bandwidth range is 1-4294967 Mbps. The different reference
bandwidth can be independently configured for OSPFv2 and OSPFv3.
Default
Format auto-cost reference-bandwidth <1 to 4294967>
Mode
no auto-cost reference-bandwidth (OSPF)
Use this command to set the reference bandwidth to the default value.
Format no auto-cost reference-bandwidth
