6.3.2.21 area virtual-link transmit-delay
area virtual-link transmit-delay 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 to 3600 (1 hour). no area virtual-link transmit-delay
command resets the default transmit delay for the OSPF virtual interface to the default value.

6.3.2.22 auto-cost
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.
Use no auto-cost command to set the reference bandwidth to the default value.
