Configuring the OSPFv3 GR Helper

Configuring the OSPFv3 GR Helper


GR is a technology used to ensure normal traffic forwarding and non-stop forwarding of key services during the restart of routing protocols. GR is one of high availability (HA) technologies. HA technologies comprise a set of comprehensive techniques, such as fault-tolerant redundancy, link protection, faulty node recovery, and traffic engineering. As a fault-tolerant redundancy technology, GR is widely used to ensure non-stop forwarding of key services during the master/slave switchover and system upgrade.


The switch can be configured as a GR helper rather than a GR restarter.

Pre-configuration Tasks

Before configuring OSPFv3 GR, complete the following tasks:

  • Configuring a link layer protocol

  • Configuring IP addresses for interfaces to ensure that neighboring nodes are reachable at the network layer

  • Configuring Basic OSPFv3 Functions


  1. Run system-view

    The system view is displayed.

  2. Run ospfv3 process-id

    The OSPFv3 view is displayed.

  3. Run helper-role [ { ip-prefix ip-prefix-name | acl-number acl-number | acl-name acl-name } | max-grace-period period | planned-only | lsa-checking-ignore ]*

    OSPFv3 GR is enabled.

    By default, the OSPFv3 GR helper function is disabled.

  4. Run commit

    The configuration is committed.

Verifying the Configuration

Run the display ospfv3 [ process-id ] graceful-restart-information command to view the OSPFv3 GR status.
