.. _ospfv3:
******
OSPFv3
******
*ospf6d* is a daemon support OSPF version 3 for IPv6 network. OSPF for IPv6 is
described in :rfc:`2740`.
.. _ospf6-router:
OSPF6 router
============
.. index:: router ospf6
.. clicmd:: router ospf6
.. index:: ospf6 router-id A.B.C.D
.. clicmd:: ospf6 router-id A.B.C.D
Set router's Router-ID.
.. index:: interface IFNAME area (0-4294967295)
.. clicmd:: interface IFNAME area (0-4294967295)
.. index:: interface IFNAME area A.B.C.D
.. clicmd:: interface IFNAME area A.B.C.D
Bind interface to specified area, and start sending OSPF packets. `area` can
be specified as 0.
.. index:: timers throttle spf DELAY INITIAL-HOLDTIME MAX-HOLDTIME
.. clicmd:: timers throttle spf DELAY INITIAL-HOLDTIME MAX-HOLDTIME
.. index:: timers throttle spf
.. clicmd:: no timers throttle spf
This command sets the initial `delay`, the `initial-holdtime`
and the `maximum-holdtime` between when SPF is calculated and the
event which triggered the calculation. The times are specified in
milliseconds and must be in the range of 0 to 600000 milliseconds.
The `delay` specifies the minimum amount of time to delay SPF
calculation (hence it affects how long SPF calculation is delayed after
an event which occurs outside of the holdtime of any previous SPF
calculation, and also serves as a minimum holdtime).
Consecutive SPF calculations will always be separated by at least
'hold-time' milliseconds. The hold-time is adaptive and initially is
set to the `initial-holdtime` configured with the above command.
Events which occur within the holdtime of the previous SPF calculation
will cause the holdtime to be increased by `initial-holdtime`, bounded
by the `maximum-holdtime` configured with this command. If the adaptive
hold-time elapses without any SPF-triggering event occurring then
the current holdtime is reset to the `initial-holdtime`.
.. code-block:: frr
router ospf6
timers throttle spf 200 400 10000
In this example, the `delay` is set to 200ms, the initial holdtime is set
to 400ms and the `maximum holdtime` to 10s. Hence there will always be at
least 200ms between an event which requires SPF calculation and the actual
SPF calculation. Further consecutive SPF calculations will always be
separated by between 400ms to 10s, the hold-time increasing by 400ms each
time an SPF-triggering event occurs within the hold-time of the previous
SPF calculation.
.. index:: auto-cost reference-bandwidth COST
.. clicmd:: auto-cost reference-bandwidth COST
.. index:: auto-cost reference-bandwidth
.. clicmd:: no auto-cost reference-bandwidth
This sets the reference bandwidth for cost calculations, where this
bandwidth is considered equivalent to an OSPF cost of 1, specified in
Mbits/s. The default is 100Mbit/s (i.e. a link of bandwidth 100Mbit/s
or higher will have a cost of 1. Cost of lower bandwidth links will be
scaled with reference to this cost).
This configuration setting MUST be consistent across all routers
within the OSPF domain.
.. _ospf6-area:
OSPF6 area
==========
Area support for OSPFv3 is not yet implemented.
.. _ospf6-interface:
OSPF6 interface
===============
.. index:: ipv6 ospf6 cost COST
.. clicmd:: ipv6 ospf6 cost COST
Sets interface's output cost. Default value depends on the interface
bandwidth and on the auto-cost reference bandwidth.
.. index:: ipv6 ospf6 hello-interval HELLOINTERVAL
.. clicmd:: ipv6 ospf6 hello-interval HELLOINTERVAL
Sets interface's Hello Interval. Default 10
.. index:: ipv6 ospf6 dead-interval DEADINTERVAL
.. clicmd:: ipv6 ospf6 dead-interval DEADINTERVAL
Sets interface's Router Dead Interval. Default value is 40.
.. index:: ipv6 ospf6 retransmit-interval RETRANSMITINTERVAL
.. clicmd:: ipv6 ospf6 retransmit-interval RETRANSMITINTERVAL
Sets interface's Rxmt Interval. Default value is 5.
.. index:: ipv6 ospf6 priority PRIORITY
.. clicmd:: ipv6 ospf6 priority PRIORITY
Sets interface's Router Priority. Default value is 1.
.. index:: ipv6 ospf6 transmit-delay TRANSMITDELAY
.. clicmd:: ipv6 ospf6 transmit-delay TRANSMITDELAY
Sets interface's Inf-Trans-Delay. Default value is 1.
.. index:: ipv6 ospf6 network (broadcast|point-to-point)
.. clicmd:: ipv6 ospf6 network (broadcast|point-to-point)
Set explicitly network type for specified interface.
OSPF6 route-map
===============
Usage of *ospfd6*'s route-map support.
.. index:: set metric [+|-](0-4294967295)
.. clicmd:: set metric [+|-](0-4294967295)
Set a metric for matched route when sending announcement. Use plus (+) sign
to add a metric value to an existing metric. Use minus (-) sign to
substract a metric value from an existing metric.
.. _redistribute-routes-to-ospf6:
Redistribute routes to OSPF6
============================
.. index:: redistribute static
.. clicmd:: redistribute static
.. index:: redistribute connected
.. clicmd:: redistribute connected
.. index:: redistribute ripng
.. clicmd:: redistribute ripng
.. _showing-ospf6-information:
Showing OSPF6 information
=========================
.. index:: show ipv6 ospf6 [INSTANCE_ID] [json]
.. clicmd:: show ipv6 ospf6 [INSTANCE_ID] [json]
INSTANCE_ID is an optional OSPF instance ID. To see router ID and OSPF
instance ID, simply type "show ipv6 ospf6 <cr>". JSON output can be
obtained by appending 'json' to the end of command.
.. index:: show ipv6 ospf6 database [<detail|dump|internal>] [json]
.. clicmd:: show ipv6 ospf6 database [<detail|dump|internal>] [json]
This command shows LSAs present in the LSDB. There are three view options.
These options helps in viewing all the parameters of the LSAs. JSON output
can be obtained by appending 'json' to the end of command. JSON option is
not applicable with 'dump' option.
.. index:: show ipv6 ospf6 database <router|network|inter-prefix|inter-router|as-external|group-membership|type-7|link|intra-prefix> [json]
.. clicmd:: show ipv6 ospf6 database <router|network|inter-prefix|inter-router|as-external|group-membership|type-7|link|intra-prefix> [json]
These options filters out the LSA based on its type. The three views options
works here as well. JSON output can be obtained by appending 'json' to the
end of command.
.. index:: show ipv6 ospf6 database adv-router A.B.C.D linkstate-id A.B.C.D [json]
.. clicmd:: show ipv6 ospf6 database adv-router A.B.C.D linkstate-id A.B.C.D [json]
The LSAs additinally can also be filtered with the linkstate-id and
advertising-router fields. We can use the LSA type filter and views with
this command as well and visa-versa. JSON output can be obtained by
appending 'json' to the end of command.
.. index:: show ipv6 ospf6 database self-originated [json]
.. clicmd:: show ipv6 ospf6 database self-originated [json]
This command is used to filter the LSAs which are originated by the present
router. All the other filters are applicable here as well.
.. index:: show ipv6 ospf6 interface [json]
.. clicmd:: show ipv6 ospf6 interface [json]
To see OSPF interface configuration like costs. JSON output can be
obtained by appending "json" in the end.
.. index:: show ipv6 ospf6 neighbor [json]
.. clicmd:: show ipv6 ospf6 neighbor [json]
Shows state and chosen (Backup) DR of neighbor. JSON output can be
obtained by appending 'json' at the end.
.. index:: show ipv6 ospf6 interface traffic [json]
.. clicmd:: show ipv6 ospf6 interface traffic [json]
Shows counts of different packets that have been recieved and transmitted
by the interfaces. JSON output can be obtained by appending "json" at the
end.
.. index:: show ipv6 ospf6 request-list A.B.C.D
.. clicmd:: show ipv6 ospf6 request-list A.B.C.D
Shows requestlist of neighbor.
.. index:: show ipv6 route ospf6
.. clicmd:: show ipv6 route ospf6
This command shows internal routing table.
.. index:: show ipv6 ospf6 zebra [json]
.. clicmd:: show ipv6 ospf6 zebra [json]
Shows state about what is being redistributed between zebra and OSPF6.
JSON output can be obtained by appending "json" at the end.
.. index:: show ipv6 ospf6 redistribute [json]
.. clicmd:: show ipv6 ospf6 redistribute [json]
Shows the routes which are redistributed by the router. JSON output can
be obtained by appending 'json' at the end.
