Controlling Ospf Link Cost Metrics; Allowing Dynamic Ospf Virtual Links - Motorola BSR 2000 Configuration And Management Manual

Release 1.0
Use the default-information originate command in Router Configuration mode to
force the ASBR to generate a default route into the OSPF routing domain:
MOT (config-ospf)#default-information originate [always] [metric
<0-16777214>] [metric-type <1-2>]
where:
Example
The following example specifies a metric of 100 for the default route redistributed
into the OSPF routing domain and an external metric type of Type 1:

Controlling OSPF Link Cost Metrics

The BSR OSPF routing process calculates the OSPF cost metric for an interface
according to the bandwidth of this interface. The cost of an interface depends on the
type of interface. The OSPF cost metric is calculated as the reference bandwidth
divided by the bandwidth of the interface.
Use the auto-cost reference-bandwidth command in Router Configuration mode to
set the automatic cost metric that the OSPF routing process uses to differentiate the
cost of multiple high-bandwidth links:
MOT (config-ospf)#auto-cost reference-bandwidth <1-4294967>
where:

Allowing Dynamic OSPF Virtual Links

Automatic detection and creation of OSPF links is disabled by default. Use the
auto-virtual-link command in Router Configuration mode if you want to allow the
OSPF routing process on the BSR to automatically detect and create OSPF virtual
links.

not have one.
0-16777214 is the metric for generating the default route; default is 10.
1-2 is the OSPF link state metric value.
