Enabling Ipv6 Is-Is Ispf; Enabling Prefix Suppression; Configuring Bfd For Ipv6 Is-Is - HP FlexFabric 12900E Series Configuration Manual

Step
6. Set the SPF calculation
interval.

Enabling IPv6 IS-IS ISPF

Step
1. Enter system view.
2. Enter IS-IS view.
3. Specify
cost style.
4. Enter IPv6 address
family view.
5. Enable IPv6 IS-IS
MTR.
6. Enable IPv6 IS-IS
ISPF.

Enabling prefix suppression

Perform this task to disable an interface from advertising its prefix in LSPs. This enhances network
security by preventing IP routing to the interval nodes and speeds up network convergence.
To enable prefix suppression:
Step
1. Enter system view.
2. Enter interface view.
3. Enable prefix suppression on
the interface.

Configuring BFD for IPv6 IS-IS

Bidirectional forwarding detection (BFD) can quickly detect faults between IPv6 IS-IS neighbors to
improve the convergence speed of IPv6 IS-IS. For more information about BFD, see High Availability
Configuration Guide.
To configure BFD for IPv6 IS-IS:
Step
1. Enter system view.
