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 | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter OSPF view. | ospf [ process-id | router-id router-id | vpn-instance vpn-instance-name ] * | N/A |
3. Enable PIC for OSPF. | pic [ additional-path-always ] | By default, OSPF PIC is enabled. |
Configuring BFD for OSPF PIC
By default, OSPF PIC does not use BFD to detect primary link failures. To speed up OSPF convergence, enable BFD for OSPF PIC to detect the primary link failures.
To configure BFD control packet mode for OSPF PIC:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter interface view. | interface interface-type interface-number | N/A |
3. Enable BFD control packet mode for OSPF PIC. | ospf primary-path-detect bfd ctrl | By default, BFD control packet mode for OSPF PIC is disabled. |
To configure BFD echo packet mode for OSPF PIC:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Configure the source IP address of BFD echo packets. | bfd echo-source-ip ip-address | By default, the source IP address of BFD echo packets is not configured. The source IP address cannot be on the same network segment as any local interface's IP address. For more information about this command, see High Availability Command Reference. |
3. Enter interface view. | interface interface-type interface-number | N/A |
4. Enable BFD echo packet mode for OSPF PIC. | ospf primary-path-detect bfd echo | By default, BFD echo packet mode for OSPF PIC is disabled. |
