Configuring Prefix Suppression On An Interface; Configuring Prefix Prioritization; Configuring Ospf Pic - HP VSR1000 Configuration Manual

Step
1. Enter system view.
2. Enter OSPF view.
3. Enable prefix
suppression for the
OSPF process.

Configuring prefix suppression on 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 on 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 to only inter-area routes and external routes.
