Command Purpose
auto-cost reference-bandwidth ref-bw Differentiate high bandwidth links.
5.7.12 Configure Route Calculation Timers
You 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.
You 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
You 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 | rip | bgp} [metric metric-value]
[metric-type {1|2}][route-map map-tag] Redistribute routes into OSPF routing domain.
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 {1|2}]
5.7.15 Generate a Default Route
You 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.
