5.10 Configuration OSPFv3 GR

By configuring OSPFv3 GR, you can avoid inaccurate route calculation and packet loss after
an OSPFv3 router restarts.

5.10.1 Establishing the Configuration Task

By default, the OSPFv3 GR capability and Helper capability are disabled.
Applicable Environment
To prevent route flapping and service interruption due to the restart of OSPFv3, you can enable
OSPFv3 GR.
Issue 01 (2012-03-15)
Run the display ospfv3 interface [ area area-id ] [ interface-type interface-number ]
command to check the OSPFv3 interface information.
Run the commands as follow to check the LSDB information about OSPFv3:
– display ospfv3 [ process-id ] lsdb [ area area-id ] [ originate-router advertising-
router-id | self-originate ] [ { router | network | inter-router [ asbr-router asbr-
router-id ] | { inter-prefix | nssa } [ ipv6-address prefix-length ] | link | intra-prefix |
grace } [ link-state-id ] ]
– display ospfv3 [ process-id ] lsdb [ originate-router advertising-router-id | self-
originate ] external [ ipv6-address prefix-length ] [ link-state-id ]
Run the commands as follow to check the OSPFv3 routing table:
– display ospfv3 [ process-id ] routing uninstalled
– display ospfv3 [ process-id ] routing [ abr-routes | asbr-routes | statistics
[ uninstalled ] | ipv6-address prefix-length | intra-routes | inter-routes | ase-routes |
nssa-routes ]
