5.7.11 Control Default Metrics

OSPF calculates the OSPF metric for an interface according to the bandwidth of the interface. For example, a 64K link gets a metric of 1562, while a T1 link gets a metric of 64.

If you have multiple links with high bandwidth, you might want to specify a larger number to differentiate the cost on those links. To do so, perform the following task in router configuration mode.

Command	Purpose
auto-cost reference-bandwidth	Differentiate high bandwidth links.

5.7.12 Configure Route Calculation Timers

The user can configure the delay time between when OSPF receives a topology change and when it starts a shortest path first (SPF) calculation.

To do this, perform the following task in router configuration mode.

Command	Purpose
timers spf spf-delay	Configure route calculation timers.

5.7.13 Refresh Timer Configuration

The originating router keeps track of the LSAs and performs refreshing LSAs when a refresh timer is reached.

The user can configure the refresh time when OSPF LSAs gets refreshed and sent out. To do this, perform the following task in router configuration mode.

Command	Purpose
refresh timer <10-1800>	Configure the refresh timer. The time value is in
	seconds.

5.7.14 Redistribute Routes into OSPF

The user can re-advertise route information in an OSPF routing domain and conditionally control the redistribution of routes between two domains by defining route maps.

Perform the following tasks associated with route redistribution in router configuration mode.

Command	Purpose
redistribute {kernel connected static	Redistribute routes into OSPF routing
rip bgp} [metric metric-value][metric-type	domain.
{12}][route-map map-tag]
default-metric number	Cause the OSPF routing protocol to use
	the same metric value for all redistributed
	routes.
default-information originate [metric
metric-value][metric-type {12}]

5.7.15 Generate a Default Route

The user can force an autonomous system boundary router to generate a default route into an OSPF routing domain. Whenever you specifically configure redistribution of routes into an OSPF routing domain, the router automatically becomes an autonomous system boundary router.

However, an autonomous system boundary router does not, by default, generate a default route into the OSPF routing domain.
