Step 3
Run:
ospfv3 mtu-ignore
[
instance
instance-id
]
The MTU check on DD packets is ignored.
After the command is used, the interface does not check the MTU field of a received DD packet.

5.9.7 Checking the Configuration
After an OSPFv3 network is optimized, you can check the OSPFv3 interface, LSDB, and routing
table.
Prerequisites
The configurations for Optimizing an OSPFv3 Network are complete.
Procedure
l
Run the
display ospfv3
interface
[
area
area-id
] [
interface-type
interface-number
]
command to check the OSPFv3 interface information.
l
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
]
l
Run the commands as follow to check the OSPFv3 routing table:
–
display ospfv3
[
process-id
]
routing
uninstalled
–
display ospfv3
[
process-id
]
routing
[
abr-routes

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.
