OSPF process.
Configuring prefix suppression for an interface
Interface prefix suppression does not suppress prefixes of secondary IP addresses.
To configure interface prefix suppression:
Step
1.
Enter system view.
2.
Enter interface
view.
3.
Enable prefix
suppression for the
interface.
Configuring prefix prioritization
This feature enables the device to install prefixes in descending priority order: critical, high, medium,
and low. The prefix priorities are assigned through routing policies. When a route is assigned multiple
prefix priorities, the route uses the highest priority.
By default, the 32-bit OSPF host routes have a medium priority and other routes a low priority.
To configure prefix prioritization:
Step
1.
Enter system view.
2.
Enter OSPF view.
3.
Enable prefix
prioritization.
Configuring OSPF PIC
Prefix Independent Convergence (PIC) enables the device to speed up network convergence by
ignoring the number of prefixes.
When both OSPF PIC and OSPF FRR are configured, OSPF FRR takes effect.
OSPF PIC applies only to inter-area routes and external routes.
Enabling OSPF PIC
Step
1.
Enter system view.
