Configuring Is-Is Pic - HP FlexFabric 12900E Series Configuration Manual

Configuring IS-IS PIC

Prefix Independent Convergence (PIC) enables the device to speed up network convergence by
ignoring the number of prefixes.
When both IS-IS PIC and IS-IS FRR are configured, IS-IS FRR takes effect.
IS-IS PIC applies only to LSPs sent by neighbors.
Enabling IS-IS PIC
Step
1. Enter system view.
2. Enter IS-IS view.
3. Enable PIC for IS-IS.
Enabling BFD for IS-IS PIC
By default, IS-IS PIC does not use BFD to detect primary link failures. To speed up IS-IS
convergence, enable BFD for IS-IS PIC to detect primary link failures.
To enable BFD control packet mode for IS-IS PIC:
Step
1. Enter system view.
2. Enter interface view.
3. Enable BFD control packet
mode for IS-IS PIC.
To configure BFD echo packet mode for IS-IS PIC:
Step
1. Enter system view.
2. Configure
address of BFD echo packets.
3. Enter interface view.
4. Enable BFD echo packet
mode for IS-IS PIC.
