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.
Syntax
area <areaid> virtual-link <neighbor> transmit-delay <seconds>
no area <areaid> virtual-link <neighbor> transmit-delay

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.
