  ip6rtrd.conf - IPv6 router daemon (ip6rtrd) configuration file


  The ip6rtrd.conf file	contains configuration information that	is read	by
  the ip6rtrd daemon at	initialization time.  This file	contains statements
  that control information sent	in router advertisements and RIPng messages.

  The ip6rtrd.conf file	consists of structured information for each interface
  in the following format:

       interface interface-name	{
	  # interface keyword-value pairs, one per line
	  Prefix prefix/length {
	      #	prefix keyword-value pairs, one	per line

  Comments begin with the number sign (#) and continue to the end of the

  The following	table lists the	keywords and range of accepted values.	See
  RFC 2461 for complete	descriptions of	the keywords.
  Keyword		  Values			       Default
  AdvSendAdvertisements	  yes/no			       yes
  MaxRtrAdvInterval	  4 - 1800 seconds		       600
  MinRtrAdvInterval	  3 - (0.75 * MaxRtrAdvInterval)       200
  AdvManagedFlag	  0/1				       0
  AdvOtherConfigFlag	  0/1				       0
  AdvLinkMTU		  non-negative integer		       0
  AdvReachableTime	  0 - 3,600,000	milliseconds	       0
  AdvRetransTimer	  non-negative integer		       0
  AdvDefaultLifetime	  0 or MaxRtrAdvInterval - 9000	secs   1800

  In addition, the following interface keywords	are accepted:

	    Specifies the value	to be placed in	the Cur	Hop Limit field	in
	    the	Router Advertisement messages sent by the router.  The value
	    zero means unspecified (by this router).  Valid values are any
	    non-negative integer.  The default is 0.

	    Sends the interface	link-layer address option in outgoing router
	    advertisements. Valid values are yes and no. The default is	yes.

	    Sends site local prefexes in outgoing router advertisements.
	    Valid values are yes and no.  The default is no.

  ripng	    Enables (yes) or disables (no) participation in RIPng on the
	    interface.	If enabled, RIPng updates are sent on the interface,
	    and	received RIPng updates are processed as	defined	in RFC 2080.
	    You	cannot specify yes for automatic tunnels (the tun0 inter-
	    face).  The	default	is yes (except for tun0).

	    Enables (1)	or disables (0)	the Split Horizon algorithm as speci-
	    fied in RFC	2080. The default is 1.

	    Enables (1)	or disables (0)	the Poisoned Reverse algorithm as
	    specified in RFC 2080.  The	default	is 1.

  Address Prefix Information

  Each address prefix to be configured on the interface	must be	defined
  within a prefix block	that begins with the keyword Prefix followed by	the
  prefix and length (separated by a slash (/)) and optionally followed by an
  additional address prefix information	block of keyword-value pairs.

  The following	table lists address prefix keywords and	values that are
  described in RFC 2461:
  Prefix Keyword	 Values	   Default
  AdvValidLifetime	 integer   2592000 seconds
  AdvPreferredLifetime	 integer   604800 seconds
  AdvOnLinkFlag		 0/1	   1
  AdvAutonomousFlag	 0/1	   1

  The following	table lists address prefix keywords and	values that are
  described in RFC 2080:
  Prefix Keyword   Values		Default
  RouteMetric	   1 - 16 (inclusive)	1
  RouteTag	   integer		0

  In addition, you can specify the following address prefix keywords:

	    The	ip6rtrd	will configure the advertised prefix on	the interface
	    if ConfigureThisPrefix is specified	and set	to 1, or if Confi-
	    gureThisPrefix is not specified and	AdvAutonomousFlag is set to

	    The	prefix is not auto-configured in all other cases.  Valid
	    values are 0 and 1.	The default value is the value of AdvAuto-
