Configuring OSPFv3 Graceful Restart
This section describes the following tasks for configuring a graceful restart of an OSPFv3 process:
• Enabling Graceful Restart, page RC-182
• Configuring the Maximum Lifetime of a Graceful Restart, page RC-182
• Configuring the Minimum Time Required Between Restarts, page RC-183
• Configuring the Helper Level of the Router, page RC-184
• Displaying Information About Graceful Restart, page RC-185
Step 3
show ospf [
process-name
] database
Example:
RP/0/RP0/CPU0:router# show ospf group2 database
(Optional) Displays the lists of information related to the
OSPF database for a specific router.
• The various forms of this command deliver information
about different OSPF LSAs.
Step 4
show ospf [
process-name
] [
area-id
] flood-list
interface
type instance
Example:
RP/0/RP0/CPU0:router# show ospf 100 flood-list
interface pos 0/3/0/0
(Optional) Displays a list of OSPF LSAs waiting to be
flooded over an interface.
Step 5
show ospf [
process-name
] [
area-id
] neighbor
[
interface-type interface-instance
]
[
neighbor-id
] [detail]
Example:
RP/0/RP0/CPU0:router# show ospf 100 neighbor
(Optional) Displays OSPF neighbor information on an
individual interface basis.
Step 6
clear ospf [
process-name
] process
Example:
RP/0/RP0/CPU0:router# clear ospf 100 process
(Optional) Resets an OSPF router process without stopping
and restarting it.
Step 7
clear ospf [
process-name
] statistics [neighbor
[
interface-type interface-instance
]
[
ip-address
]]
Example:
RP/0/RP0/CPU0:router# clear ospf 100 statistics
(Optional) Clears the OSPF statistics of neighbor state
transitions.
