Configuring OSPF Route Control 329
n
If the cost value is not configured for an interface, OSPF computes the interface
cost automatically: Interface cost= Bandwidth reference value/Interface
bandwidth. If the calculated cost is greater than 65535, the value of 65535 is
used.
Configuring the
Maximum Number of
OSPF Routes
To configure the maximum number of routes, use the following commands:
Configuring the
Maximum Number of
Equal Cost Routes for
Load Balancing
If several routes with the same cost to the same destination are available,
configuring them as load-balanced routes can improve link utilization.
To configure the maximum number of equal cost routes, use the following
commands:
Configuring the Priority
of OSPF Routes
A router may run multiple routing protocols. The router sets a priority for each
protocol, when a route found by several routing protocols, the route found by the
protocol with the highest priority will be selected.
To configure the priority for OSPF, use the following commands:
Configure a bandwidth
reference value
