  Message : add "fib reload" support to ospf6d/ospf6ctl, and trigger it automatically on a timeout after RTM_DESYNC (i.e. route socket overflow). ported across from ospfd. fixes/ok claudio@ (it's much harder to overflow the routing socket buffer these days since it was bumped to 2MB, but still happens occasionally on a busy machine).

  .Os
  .Sh NAME
  .Nm ospf6ctl
  .Nd control the OSPF for IPv6 routing daemon
  .Sh SYNOPSIS
  .Nm
  .Op Fl s Ar socket
  .Ar command
  .Op Ar argument ...
  .Sh DESCRIPTION
  The
  .Nm
  program controls the
  .Xr ospf6d 8
  daemon.
  .Pp
  The following options are available:
  .Bl -tag -width Ds
  .It Fl s Ar socket
  Use
  .Ar socket
  instead of the default
  .Pa /var/run/ospf6d.sock
  to communicate with
  .Xr ospfd 8 .
  .El
  .Pp
  Commands may be abbreviated to the minimum unambiguous prefix; for example,
  .Cm s s
  for
  .Cm show summary .
  .Pp
  The following commands are available:
  .Bl -tag -width Ds
  .It Cm fib couple
  Insert the learned routes into the Forwarding Information Base (FIB),
  a.k.a. the kernel routing table.
  .It Cm fib decouple
  Remove the learned routes from the FIB.
  Decoupling the FIB from an OSPF router may create routing loops and could cause
  major routing issues in the complete OSPF cloud.
  Only routers with just one link to the OSPF cloud can safely decouple the FIB.
  .It Cm fib reload
  Refetches and relearns the routes in the Forwarding Information Base
  a.k.a. the kernel routing table.
  .It Cm log brief
  Disable verbose debug logging.
  .It Cm log verbose
  Enable verbose debug logging.
  .It Cm reload
  Reload the configuration file.
  This command currently has no effect.
  .It Cm show database Op Ar filter
  Show the link state database.
  .Ar filter
  can be any one of the following:
  .Pp
  .Bl -tag -width "self-originatedXX" -compact
  .It Cm area Ar ID
  Show only LSAs from the specified area
  .Ar ID .
  .It Cm asbr
  Show only ASBR LSAs.
  .It Cm external
  Show only AS-External LSAs.
  .It Cm intra
  Show only Intra-Area-Prefix LSAs.
  .It Cm link
  Show only Link LSAs.
  .It Cm network
  Show only Network LSAs.
  .It Cm router
  Show only Router LSAs.
  .It Cm self-originated
  Show only self-originated LSAs.
  .It Cm summary

  .El
  .It Cm show fib Op Ar destination | filter
  Show the Forwarding Information Base.
  .Ar destination
  can be specified to show the route matching a destination IP address.
  .Ar filter
  can be any of the following:
  .Pp
  .Bl -tag -width "interfaceXXinterfaceXX" -compact
  .It Cm connected
  Show only connected routes.
  .It Cm interface Op Ar interface
  Show only interfaces or the specified
  .Ar interface .
  .It Cm ospf
  Show only OSPF routes.
  .It Cm static
  Show only static routes.
  .El
  .Pp
  .Cm connected ,
  .Cm ospf
  and
  .Cm static
  may be specified together.
  .It Cm show interfaces Op Ar interface
  Show details for all interfaces or the specified
  .Ar interface .
  .It Cm show neighbor Op Cm detail
  Show neighbors.
  .Cm detail
  can be specified for additional detail.
  .It Cm show rib Op Cm detail
  Show the Routing Information Base.
  .Cm detail
  can be specified for additional detail.
  .It Cm show summary
  Show summary information.
