This file consists of a sequence of statements terminated by a semi-colon (`;'). Statements are composed of tokens separated by white space, which can be any combination of blanks, tabs and newlines. This structure simplifies identification of the parts of the configuration associated with each other. Lines beginning with .Ql # are comments. .\" .Sh Meta Syntax Keywords and special characters that the parser expects exactly are displayed using the .Ic bold font. Parameters are specifying with .Ar underline . Parameters shown in square brackets (`[' and `]') are used to show optional keywords and parameters. The vertical bar (`|') is used to indicate between a choice of optional parameters. Parentheses (`(' and `)') are used to group keywords and parameters when necessary. .\" .Sh Interface specification There are some statements that may or have to specify interface. Interfaces are specified in the form of "name unit", such as .Ar lo0 and .Ar ep1. .\" .Sh Configuration Statements .Bl -tag -width Ds .\" .It Ic debug on|off ; Enables configuration file parser debugging. If .Ic on is specified, then debugging is enabled, If .Ic off is specified, then debugging is disabled. It is disabled by default. .\" .It Ic dest Ar dest-list Op Ar retrycmd ; Specifies destinations to which router renumbering messages should be sent. .Ar dest-list can be any combination of single or multiple numerical IPv6 addrs, or Full Qualified Domain Names. .Ar retrycmd has following syntax. .\" .Bl -tag -width Ds -compact .It Ic retry Ar retry-num .Ar retry-num specifies how many router renumbering messages are sent repeatedly. .El .It Op Ic add|change|setglobal .Cm match-prefix Ar match-prefix-val .Op /match-prefix-len .Op Cm maxlen Ar maxlen-val .Op Cm minlen Ar minlen-val .Op Cm use-prefix Ar use-prefix-val .Op /use-prefix-len .Op Cm keeplen Ar keeplen-val .Op Ar use-prefix-values ; .Pp Specifies contents of sending router renumbering message with seqnum 0. If .Cm add|change|setglobal is not specified, then .Cm add is assumed. .Ar use-prefix-values has following syntax. .Pp { .Op Cm vltime Ar vltime-val .Op Cm pltime Ar pltime-val .Op Cm raf_onlink Cm on|off .Op Cm raf_auto Cm on|off .Op Cm rrf_decrprefd Cm on|off .Op Cm rrf_decrvalid Cm on|off } .Pp Each value has following meaning. .Pp .Bl -tag -width Ds -compact .It Cm match-prefix Ar match-prefix-val Op /match-prefix-len Specify .Ar match-prefix-val that is used for matching with preassigned prefixes to which .Cm add|change|setglobal command should be applied. .Ar /match-prefix-len Specify the starting part of .Ar match-prefix-val to be used for matching with preassigned prefixes, as decimal bit number. .It Cm maxlen Ar maxlen-val Specify the maximum length of prefixes which is allowed to be matched to .Ar match-prefix-val , as decimal bit number. .It Cm minlen Ar minlen-val Specify the minimum length of prefixes which is allowed to be matched to .Ar match-prefix-val , as decimal bit number. .It Cm use-prefix Ar use-prefix-val Op /usr-prefix-len Specify .Ar use-prefix-val that is used for prefixes to be added on .Cm add|change|setglobal command. .Ar /use-prefix-len Specify the starting part of .Ar use-prefix-val copied to the starting part of prefixes to be added on .Cm add|change|setglobal command, as decimal bit number. .It Cm keeplen Ar keeplen-val Specify the midium part of .Ar use-prefix-val just next to the starting part specified by .Ar use-prefix-len , as decimal bit number. Contiguous bits part in the same bit position of an existent prefix matched with .Ar match-prefix-val is copied to the same bit position of prefixes to be added. .It Cm vltime Ar vmtime-val Assign an .Ar time as prefix valid life time for a prefix to be added. Valid value for .Ar time is decimal seconds number or special format as "d00h00m00s00", where 00 can take any decimal number, and "d" means days, "h" means hours, "m" means minutes, "s" means seconds. And alternatively, special keyword "infinity" can be also be specified. .It Cm pltime Ar pltime-val Assign an .Ar time as prefix preferred life time for a prefix to be added. Valid value for .Ar time is same as for .Ar vltime-val . .It Cm raf_onlink Cm on|off Let the prefix to be added to have on-link or off-link nature for the assigned interface. If .Cm on is specified, the prefix have on-link nature. (e.g. the prefix belong to the link) If .Cm off is specified, the prefix have off-link nature. (e.g. the prefix does not belong to the link) .It Cm raf_auto Cm on|off Enable or disable the autonomous address auto configuration for the prefix to be added. If .Cm on is specified, autonomous address auto configuration is enabled. If .Cm off is specified, it is disabled. .It Cm rrf_decrprefd Cm on|off Enable or disable the decrementation of the pltime. If .Cm on is specified, decrementation of the pltime is enabled. If .Cm off is specified, decrementation of the pltime is disabled. .It Cm rrf_decrvalid Cm on|off Enable or disable the decrementation of the vltime. If .Cm on is specified, decrementation of the vltime is enabled. If .Cm off is specified, decrementation of the vltime is disabled. .El .\" .It seqnum Ar seqnum-val { Ar rrenum-cmd } ; Specifies contents of sending router renumbering message with some specific seqnum. Multiple of this statement can be specified if they have different .Ar seqnum-val each other. .Ar rrenum-cmd has just same syntax with above add|change|setglobal statement. .El .\" .Sh EXAMPLE For each configuration file example shown below, we suppose every IPv6 subnet has its own prefix beginning with fec0:0:0::/48 and with its own subnet number. (in this case, subnet number is 7th and 8th octet value of the prefix) .Pp If you want to assigne prefixes beginning with fec0:1:1::/48 to each subnet, then following configuration will be enough, if each of your routers supports IPv6 multicast forwarding. The subnet number of the existing fec0:0:0::/48 prefix and the newly assigned fec0:1:1::/48 prefix will be same. .\" .Bd -literal -offset indent dest ff05::2; add match-prefix fec0:0:0:: /48 use-prefix fec0:1:1:: /48 keeplen 16; .Ed .\" If your routers don't support IPv6 multicast forwarding, you'll need to specify each destination at .Cm dest command. .\" .Bd -literal -offset indent dest fec0:0:0:1:260:8ff:fe24:fb3a fec0:0:0:2:200:eff:fe2e:dfe1 fec0:0:0:3:5254:ff:fedc:5217; add match-prefix fec0:0:0:: /48 use-prefix fec0:1:1:: /48 keeplen 16; .Ed .\" If you are going to do renumbering, then following procedure will be natural. .Bl -enum -offset indent .It Assigne new prefix. .It Set old prefix lifetimes to some appropriate transition period. In the followng example we use 1 week for valid lifetime, and 0 for preferred lifetime. Also, enable old prefix lifetime expiration. (By default, it is static and does not expire) .It After the transition period, old prefixes should become invalid, and may have been deleted. To make sure that they are deleted, send new router renumbering message, which specifies old prefixes as match prefix, and no use prefix. .El .\" The following configuration file will do 1 and 2. .\" .Bd -literal -offset indent dest ff05::2; seqnum 0 { add match-prefix fec0:0:0:: /48 use-prefix fec0:2:2:: /48 keeplen 16; }; seqnum 1 { change match-prefix fec0:1:1:: /48 use-prefix fec0:1:1:: /48 keeplen 16 vltime d7 pltime 0 rrf_decrvalid on rrf_decrprefd on; }; .Ed .\" And the following configuration file will do 3. (should be used for the router renumbering message to be sent 1 week afterward) .\" .Bd -literal -offset indent dest ff05::2; change match-prefix fec0:1:1:: /48; .Ed .\" In the above example, only .Cm add and .Cm change commands are used, and there is no example for .Cm setglobal command. .Cm setglobal command is almost same with .Cm change command except that it deletes all pre-defined IPv6 global address. .Sh SEE ALSO .Xr rrenumd 8 .Xr prefix 8 .Sh HISTORY The .Nm configuration file was first appeared in KAME IPv6 protocol stack kit. .\" .Sh BUGS .\" (to be written)
