no area <areaid> virtual-link <neighbor> hello-interval
Default 10
Mode Router OSPF Config
6.3.2.20. area virtual-link retransmit-interval
area virtual-link retransmit-interval command configures the retransmit interval 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. no area virtual-link retransmit -interval command configures the
default retransmit interval for the OSPF virtual interface on the virtual interface identified by <areaid> and
<neighbor>. The <neighbor> parameter is the Router ID of the neighbor.
Format area <areaid> virtual-link <neighbor> retransmit-interval <seconds>
no area <areaid> virtual-link <neighbor> retransmit-interval
Default 5
Mode Router OSPF Config
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.
Format area <areaid> virtual-link <neighbor> transmit-delay <seconds>
no area <areaid> virtual-link <neighbor> transmit-delay
Default 1
Mode Router OSPF Config
6.3.2.22. auto-cost reference-bandwidth
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
