NAME

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

DESCRIPTION

       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 line.

       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: 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.
       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 interface).	The default is yes
       (except	for  tun0).   Enables  (1) or disables (0) the Split Horizon algorithm as specified 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 ConfigureThisPrefix is not specified and AdvAutonomousFlag is set to 1.

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