OSPFv3
******

*ospf6d* is a daemon support OSPF version 3 for IPv6 network. OSPF for
IPv6 is described in **RFC 2740**.


OSPF6 router
============

router ospf6

ospf6 router-id A.B.C.D

   Set router's Router-ID.

interface IFNAME area AREA

   Bind interface to specified area, and start sending OSPF packets.
   *area* can be specified as 0.

timers throttle spf DELAY INITIAL-HOLDTIME MAX-HOLDTIME

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*.

      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.

auto-cost reference-bandwidth COST

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
==========

Area support for OSPFv3 is not yet implemented.


OSPF6 interface
===============

ipv6 ospf6 cost COST

   Sets interface's output cost. Default value depends on the
   interface bandwidth and on the auto-cost reference bandwidth.

ipv6 ospf6 hello-interval HELLOINTERVAL

   Sets interface's Hello Interval. Default 10

ipv6 ospf6 dead-interval DEADINTERVAL

   Sets interface's Router Dead Interval. Default value is 40.

ipv6 ospf6 retransmit-interval RETRANSMITINTERVAL

   Sets interface's Rxmt Interval. Default value is 5.

ipv6 ospf6 priority PRIORITY

   Sets interface's Router Priority. Default value is 1.

ipv6 ospf6 transmit-delay TRANSMITDELAY

   Sets interface's Inf-Trans-Delay. Default value is 1.

ipv6 ospf6 network (broadcast|point-to-point)

   Set explicitly network type for specified interface.


Redistribute routes to OSPF6
============================

redistribute static

redistribute connected

redistribute ripng


Showing OSPF6 information
=========================

show ipv6 ospf6 [INSTANCE_ID]

   INSTANCE_ID is an optional OSPF instance ID. To see router ID and
   OSPF instance ID, simply type "show ipv6 ospf6 <cr>".

show ipv6 ospf6 database

   This command shows LSA database summary. You can specify the type
   of LSA.

show ipv6 ospf6 interface

   To see OSPF interface configuration like costs.

show ipv6 ospf6 neighbor

   Shows state and chosen (Backup) DR of neighbor.

show ipv6 ospf6 request-list A.B.C.D

   Shows requestlist of neighbor.

show ipv6 route ospf6

   This command shows internal routing table.

show ipv6 ospf6 zebra

   Shows state about what is being redistributed between zebra and
   OSPF6


OSPF6 Configuration Examples
============================

Example of ospf6d configured on one interface and area:

   interface eth0
    ipv6 ospf6 instance-id 0
   !
   router ospf6
    ospf6 router-id 212.17.55.53
    area 0.0.0.0 range 2001:770:105:2::/64
    interface eth0 area 0.0.0.0
   !
