OSPF6D.CONF(5)              BSD File Formats Manual             OSPF6D.CONF(5)

NAME
     ospf6d.conf -- Open Shortest Path First daemon configuration file

DESCRIPTION
     The ospf6d(8) daemon implements the Open Shortest Path First protocol
     version 3 as described in RFC 5340.

SECTIONS
     The ospf6d.conf config file is divided into three main sections.

     Macros
           User-defined variables may be defined and used later, simplifying
           the configuration file.

     Global Configuration
           Global settings for ospf6d(8).  A number of global settings can be
           overruled in specific areas or interfaces.

     Areas
           An OSPF router must be a member of at least one area.  Areas are
           used to group interfaces, simplifying configuration.

     Argument names not beginning with a letter, digit, or underscore must be
     quoted.

     Additional configuration files can be included with the include keyword,
     for example:

           include "/etc/ospf6d.sub.conf"

MACROS
     Macros can be defined that will later be expanded in context.  Macro
     names must start with a letter, digit, or underscore, and may contain any
     of those characters.  Macro names may not be reserved words (for example,
     area, interface, or hello-interval).  Macros are not expanded inside
     quotes.

     For example:

           hi="5"
           area 0.0.0.0 {
                   interface em0 {
                           hello-interval $hi
                   }
           }

     The same can be accomplished by specifying the hello-interval globally or
     within the area declaration.

GLOBAL CONFIGURATION
     All interface related settings can be configured globally, per area and
     per interface.  The only settings that can be set globally and not over-
     ruled are listed below.

     fib-update (yes|no)
             If set to no, do not update the Forwarding Information Base,
             a.k.a. the kernel routing table.  The default is yes.  Setting
             fib-update to no will implicitly set the stub router option to
             ensure that no traffic tries to transit via this router.

     [no] redistribute (static|connected|default) [set ...]
     [no] redistribute prefix [set ...]
     [no] redistribute rtlabel label [set ...]
             If set to connected, routes to directly attached networks will be
             announced over OSPF.  If set to static, static routes will be
             announced over OSPF.  If set to default, a default route pointing
             to this router will be announced over OSPF.  It is possible to
             specify a network range with prefix; networks need to be part of
             that range to be redistributed.  Additionally it is possible to
             redistribute based on route labels using the rtlabel keyword.  By
             default no additional routes will be announced over OSPF.

             redistribute statements are evaluated in sequential order, from
             first to last.  The first matching rule decides if a route should
             be redistributed or not.  Matching rules starting with no will
             force the route to be not announced.  The only exception is
             default, which will be set no matter what, and additionally no
             cannot be used together with it.

             It is possible to set the route metric and type for each redis-
             tribute rule.  type is either 1 or 2.  The default value for type
             is 1 and for metric is 100.  Setting more than one option needs
             curly brackets:

                   redistribute static set { metric 300 type 2 }

     router-id address
             Set the router ID; if not specified, the lowest IPv4 address of
             the interfaces used by ospf6d(8) will be used.  A router ID must
             be specified if no IPv4 address is configured on any interfaces
             used by ospf6d(8).

     rtlabel label external-tag number
             Map route labels to external route tags and vice versa.  The
             external route tag is a non-negative 32-bit number attached to
             AS-external OSPF LSAs.

     spf-delay seconds
             Set SPF delay in seconds.  The delay between receiving an update
             to the link state database and starting the shortest path first
             calculation.  The default value is 1; valid range is 1-10 sec-
             onds.

     spf-holdtime seconds
             Set the SPF holdtime in seconds.  The minimum time between two
             consecutive shortest path first calculations.  The default value
             is 5 seconds; the valid range is 1-5 seconds.

     stub router (yes|no)
             If set to yes, all interfaces with active neighbors will have a
             metric of infinity.  This ensures that the other routers prefer
             routes around this router while still being able to reach
             directly connected IP prefixes.  The stub router option is auto-
             matically enabled if either the sysctl(8) variable
             net.inet.ip.forwarding is set to a value different to 1 or if the
             FIB is not coupled.

AREAS
     Areas are used for grouping interfaces.  All interface-specific parame-
     ters can be configured per area, overruling the global settings.

     area address
             Specify an area section, grouping one or more interfaces.

                   area 0.0.0.0 {
                           interface em0
                           interface em1 {
                                   metric 10
                           }
                   }

     Area specific parameters are listed below.

     demote group [count]
             Increase the carp(4) demotion counter by count on the given
             interface group, usually carp, when no neighbor in the area is in
             an active state.  The demotion counter will be decreased when one
             neighbor in that area is in an active state.  The default value
             for count is 1.

             For more information on interface groups, see the group keyword
             in ifconfig(8).

INTERFACES
     Each interface can have several parameters configured individually, oth-
     erwise they are inherited.  An interface is specified by its name.

           interface em0 {
                   ...
           }

     Interface-specific parameters are listed below.

     demote group
             Increase the carp(4) demotion counter by 1 on the given interface
             group, usually carp, when the interface state is going down.  The
             demotion counter will be decreased when the interface state is
             active again.

     hello-interval seconds
             Set the hello interval.  The default value is 10; valid range is
             1-65535 seconds.

     metric cost
             Set the interface metric a.k.a. cost.  The default value is 10;
             valid range is 1-65535.

     passive
             Prevent transmission and reception of OSPF packets on this inter-
             face.  The specified interface will be announced as a stub net-
             work.

     retransmit-interval seconds
             Set retransmit interval.  The default value is 5 seconds; valid
             range is 5-3600 seconds.

     router-dead-time seconds
             Set the router dead time, a.k.a. neighbor inactivity timer.  The
             default value is 40 seconds; valid range is 2-65535 seconds.
             When a neighbor has been inactive for router-dead-time its state
             is set to DOWN.  Neighbors that have been inactive for more than
             24 hours are completely removed.

     router-priority priority
             Set the router priority.  The default value is 1; valid range is
             0-255.  If set to 0 the router is not eligible as a Designated
             Router or Backup Designated Router.

     transmit-delay seconds
             Set the transmit delay.  The default value is 1; valid range is
             1-3600 seconds.
