*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:: no 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:: no 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.
