       ndpd.conf - configuration file for IPv6 router autoconfiguration


       The  ndpd.conf  file  contains  configuration information for in.ndpd(1M). On a host, this
       file does not need to exist or can be empty. The file  has  one	configuration  entry  per
       line;  note  that  lines can be extended with a backslash (\) followed by a NEWLINE. There
       are four forms of configuration entries which are identified by the  first  field  on  the
       line:  ifdefault, prefixdefault, if, or prefix. The ifdefault and if entries set interface
       configuration variables. The former establishes the routing behavior for  all  interfaces,
       the  latter  sets  per-interface  parameters.  Any  ifdefault  entries must precede any if
       entries in the file.

       The prefixdefault and prefix entries control prefix configuration variables. prefixdefault
       establishes the default behavior for all prefix advertisements on all interfaces. The pre-
       fix keyword advertises per-prefix information. Any prefixdefault entries must precede  any
       prefix entries in the file.

       Each ifdefault entry is composed of a single line of the form:

	 ifdefault [ if-variable-name value ]*

       Each if entry is composed of a single line of the form:

	 if interface [ if-variable-name value ]*

       Each prefixdefault entry is composed of a single line of the form:

	 prefixdefault [ prefix-variable-name value ]*

       Each prefix entry is composed of a single line of the form:

	 prefix prefix/prefix_length interface [ prefix-variable-name value ]*

       Fields  are separated by either SPACE or TAB characters. A `#' (number sign) indicates the
       beginning of a comment. Characters up to the end of the line are not interpreted  by  rou-
       tines that search this file.

       interface	       The name of a network interface, for example, eri0.

       prefix		       An  IPv6  address  in  standard hexadecimal notation, for example,

       prefix_length	       A number between 0 and 128.

       if-variable-name        An interface variable. Below is the list  of  interface	variables
			       applicable  to  routers	only  along with their default values and
			       units as discussed in RFC 2461 and RFC 2462.  The  Tmp*	variables
			       apply to hosts and routers. The Tmp* variables configure temporary
			       address functionality as defined in RFC 3041.

				 Variable Name		 Default    Unit

				 AdvSendAdvertisements	 false	    Boolean
				 DupAddrDetectTransmits  1	    Counter
				 MaxRtrAdvInterval	 600	    Seconds
				 MinRtrAdvInterval	 200	    Seconds
				 AdvManagedFlag 	 false	    Boolean
				 AdvOtherConfigFlag	 false	    Boolean
				 AdvLinkMTU		 0	    Bytes
				 AdvReachableTime	 0	    Milliseconds
				 AdvRetransTimer	 0	    Milliseconds
				 AdvCurHopLimit 	 see below  Counter
				 AdvDefaultLifetime	 1800	    Seconds

			       These variables are described as follows:

			       AdvSendAdvertisements	 Indicates whether the node  should  send
							 out advertisements and respond to router
							 solicitations. You  need  to  explicitly
							 configure  this  value to turn on router
							 advertisement functions.

			       DupAddrDetectTransmits	 Defines the number of consecutive Neigh-
							 bor   Solicitation   messages	that  the
							 Neighbor Discovery protocol should  send
							 during  Duplicate  Address  Detection of
							 the local node's address.

			       MaxRtrAdvInterval	 Specifies  the  maximum  time	to   wait
							 between  sending  unsolicited	multicast

			       MinRtrAdvInterval	 Specifies the minimum amount of time  to
							 wait  between sending unsolicited multi-
							 cast advertisements.

			       AdvManagedFlag		 Indicates the value to be placed in  the
							 "Manage  address  configuration" flag in
							 the  Router  Advertisement.  This   flag
							 causes  hosts	to  run DHCPv6 to acquire
							 addresses and other configuration infor-
							 mation.  This	flag  causes hosts to run
							 DHCPv6 to acquire configuration informa-
							 tion,	but only if AdvManagedFlag is not

			       AdvOtherConfigFlag	 Indicates the value to be placed in  the
							 "Other  stateful  configuration"flag  in
							 the Router Advertisement.

			       AdvLinkMTU		 Specifies an MTU value to be sent by the
							 router.  The  default	of zero indicates
							 that the router  does	not  specify  MTU

			       AdvReachableTime 	 Specifies  the  value	in  the Reachable
							 Time field in the advertisement messages
							 sent by the router.

			       AdvRetransTimer		 Specifies the value in the Retrans Timer
							 field in the advertisement messages sent
							 by the router.

			       AdvCurHopLimit		 Specifies  the value to be placed in the
							 current hop limit field  in  the  adver-
							 tisement  messages  sent  by the router.
							 The default is the current  diameter  of
							 the Internet.

			       AdvDefaultLifetime	 Specifies  the  default  lifetime of the
							 router advertisements.

			       Listed below is the interface variable that applies to both  hosts
			       and routers.

				 Variable Name		 Default    Unit

				 StatefulAddrConf	 true	    Boolean
				 StatelessAddrConf	 true	    Boolean
				 TmpAddrsEnabled	 false	    Boolean
				 TmpValidLifetime	 604800     Seconds
							 (1 week)
				 TmpPreferredLifetime	 86400	    Seconds
							 (1 day)
				 TmpRegenAdvance	 5	    Seconds
				 TmpMaxDesyncFactor	 600	    Seconds

			       StatefulAddrConf        Controls whether the system configures its
						       IPv6 addresses by means	of  the  Stateful
						       Address	Autoconfiguration mechanism, also
						       known as DHCPv6, as described in RFC 3315.
						       If  enabled (the default), hosts automati-
						       cally run DHCPv6 based  on  the	"managed"
						       and "other" flags sent by routers. If dis-
						       abled,  in.ndpd	will  not  invoke  DHCPv6
						       automatically. DHCPv6 can still be invoked
						       manually by using ifconfig(1M),	in  which
						       case in.ndpd automatically sets the prefix
						       length as needed.

			       StatelessAddrConf       Controls whether the system configures its
						       IPv6  addresses	by means of the Stateless
						       Address	  Autoconfiguration	mechanism
						       described  in  RFC  2462. If enabled hosts
						       (the  default)	autoconfigure	addresses
						       based  on  prefixes advertised by routers,
						       routers will only autoconfigure	addresses
						       based on the prefixes they advertise them-
						       selves. In other words, even when enabled,
						       routers	do  not  autoconfigure	addresses
						       based  on  prefixes  that  other   routers
						       advertise.  If  you specify false for this
						       variable, then the address must be config-
						       ured manually.

			       TmpAddrsEnabled	       Indicates   whether  a  temporary  address
						       should be created for  all  interfaces  or
						       for a particular interface of a node.

			       TmpValidLifetime        Sets  the  valid  lifetime for a temporary

			       TmpPreferredLifetime    Sets the preferred lifetime of a temporary

			       TmpRegenAdvance	       Specifies  the  lead  time  in  advance of
						       address deprecation for	generation  of	a
						       new temporary address.

			       TmpMaxDesyncFactor      Sets  the upper bound on the DesyncFactor,
						       which is a random value that  is  used  to
						       shorten	the  preferred	lifetime  so that
						       clients do not regenerate  an  address  at
						       the same time.

       prefix-variable-name    A prefix variable as discussed in RFC 2461  and RFC 2462. The fol-
			       lowing lists the each interface variable and its default value and

			       |       Variable Name	     |	 Default      |     Unit      |
			       |AdvValidLifetime	     |2592000	      |Seconds	      |
			       |AdvOnLinkFlag		     |true	      |Boolean	      |
			       |AdvPreferredLifetime	     |604800	      |Seconds	      |
			       |AdvAutonomousFlag	     |true	      |Boolean	      |
			       |AdvValidExpiration	     |not set	      |Date/Time      |
			       |AdvPreferredExpiration	     |not set	      |Date/TIme      |
			       These variables are described as follows:

			       AdvValidLifetime 	 Specifies the valid lifetime of the pre-
							 fix that is being configured.

			       AdvOnLinkFlag		 Specifies the value to be placed in  the
							 on-link flag ("L-bit") field in the Pre-
							 fix Information option.

			       AdvPreferredLifetime	 Specifies the value to be placed in  the
							 Preferred  Lifetime in the Prefix Infor-
							 mation option.

			       AdvAutonomousFlag	 Specifies the value to be placed in  the
							 Autonomous  Flag  field  in  the  Prefix
							 Information option.

			       AdvValidExpiration	 Specifies the valid expiration  date  of
							 the prefix.

			       AdvPreferredExpiration	 Specifies  the preferred expiration date
							 of the prefix.

			       The AdvValidExpiration and  AdvPreferredExpiration  variables  are
			       used  to  specify  that the lifetime should be decremented in real
			       time as specified in RFC 2461. If an Expiration variable  is  set,
			       it  takes  precedence  over  the corresponding AdvValidLifetime or
			       AdvPreferredLifetime variable setting.

       value		       The value is a function of the  unit.  Boolean  values  are  true,
			       false, on, off, 1, or 0.

			       Values  in  seconds can have characters appended for day (d), hour
			       h), minute (m) and second(s). The default is seconds. For example,
			       1h means 1 hour. This is equivalent to the value 3600.

			       Values  in  milliseconds  can  have  characters	appended  for day
			       (d),hour (h), minute (m)  second  (s),and  millisecond  (ms).  The
			       default	is  milliseconds.  For	example,  1h is equivalent to the
			       value 3600000.

			       Date/time values are strings that use  the  recommended	ISO  date
			       format  described  as  "%Y-%m-%d  %R",  which represents a 4 digit
			       year, a dash character, a numeric month, a dash character,  and	a
			       numeric day of the month, followed by one or more whitespace char-
			       acters and finally a 24 hour clock with hours, a colon,	and  min-
			       utes.  For example, 1999-01-31 20:00 means 8pm January 31 in 1999.
			       Since the date/time values contain a space, use single  or  double
			       quotes to declare the value. For example:

				 prefixdefault AdvPreferredExpiration '1999-01-31 20:00'

       Example 1 Sending Router Advertisements for all Interfaces

       The following example can be used to send router advertisements out to all interfaces:

	 # Send router advertisements out all interfaces
	 ifdefault AdvSendAdvertisements on
	 prefixdefault AdvOnLinkFlag on AdvAutonomousFlag on

	 # Advertise a (bogus) global prefix and a site
	 # local prefix on three interfaces using the default lifetimes
	 prefix 2:0:0:9255::0/64      eri0
	 prefix fec0:0:0:9255::0/64   eri0

	 prefix 2:0:0:9256::0/64      eri1
	 prefix fec0:0:0:9256::0/64   eri1

	 prefix 2:0:0:9259::0/64      eri2
	 prefix fec0:0:0:9259::0/64   eri2
