HP Moonshot Switch Module CLI Command Reference
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 to
3600 (1 hour).
no area virtual-link transmit-delay
This command resets the default transmit delay for the OSPF virtual interface to the default value.
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.
no auto-cost reference-bandwidth (OSPF)
Use this command to set the reference bandwidth to the default value.
