10.4.2.26 area virtual-link transmit-delay
This command configures the transmit delay for the OSPF virtual interface on the virtual interface
identified by <areaid> and <neighborid>.
Syntax
area <areaid> virtual-link <neighborid> transmit-delay <0-3600>
no area <areaid> virtual-link <neighborid> transmit-delay
<areaid> - Area ID.
<neighborid> - Router ID of the neighbor.
<0-3600> - The range of the transmit delay is 0 to 3600.
no - This command configures the default transmit delay for the OSPF virtual interface on the virtual
interface identified by <areaid> and <neighborid>.
Default Setting
1 second.
Command Mode
Router OSPFv3 Config
10.4.2.27 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.
Syntax
auto-cost reference-bandwidth <1 to 4294967>
no auto-cost reference-bandwidth
Default Setting
100Mbps
