Configuring OSPF
526360-001-00 Rev. B
MGBI
11-15
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:
always
indicates always advertise the default route even when the software does
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.
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:
router ospf
redistribute rip metric 100 subnets
default-information originate always metric 100 metric-type1
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:
1-4294967
is the reference bandwidth in Mbps.
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.
MOT
(config-ospf)#
auto-virtual-link
