37 .Nd configuration file for router renumbering daemon
40 The rrenumd config file describes how the router renumbering packet
41 must be constructed and to which destinations it should be sent.
42 This file consists of a sequence of statements terminated by a semi-colon (`;').
43 Statements are composed of tokens
44 separated by white space, which can be any combination of blanks, tabs
46 This structure simplifies identification of
47 the parts of the configuration associated with each other.
53 Keywords and special characters that the parser expects exactly are
57 Parameters are specifying with
60 square brackets (`[' and `]') are used to show optional
61 keywords and parameters.
62 The vertical bar (`|') is used to indicate
63 between a choice of optional parameters.
65 `}') are used to group keywords and parameters when necessary.
67 .Sh Interface specification
68 There are some statements that may or have to specify interface.
69 Interfaces are specified in the form of "name unit", such as

175 is copied to the same bit position of prefixes to be added.
176 .It Cm vltime Ar vmtime-val
179 as prefix valid life time for a prefix to be added.
182 is decimal seconds number or special format as "d00h00m00s00",
183 where 00 can take any decimal number, and "d" means days, "h" means hours,
184 "m" means minutes, "s" means seconds.
185 And alternatively, special keyword
186 "infinity" can be also be specified.
187 .It Cm pltime Ar pltime-val
190 as prefix preferred life time for a prefix to be added.
195 .It Cm raf_onlink Cm on|off
196 Let the prefix to be added to have on-link or off-link nature
197 for the assigned interface.
200 is specified, the prefix have on-link nature.
202 belong to the link) If
204 is specified, the prefix have off-link nature.
206 prefix does not belong to the link)
207 .It Cm raf_auto Cm on|off
208 Enable or disable the autonomous address auto configuration
209 for the prefix to be added.
212 is specified, autonomous address auto configuration is
216 is specified, it is disabled.
217 .It Cm rrf_decrprefd Cm on|off
218 Enable or disable the decrementation of the pltime.
221 is specified, decrementation of the pltime is enabled.
224 is specified, decrementation of the pltime is disabled.
225 .It Cm rrf_decrvalid Cm on|off
226 Enable or disable the decrementation of the vltime.
229 is specified, decrementation of the vltime is enabled.
232 is specified, decrementation of the vltime is disabled.
235 .It seqnum Ar seqnum-val { Ar rrenum-cmd } ;
236 Specifies contents of sending router renumbering message with some
238 Multiple of this statement can be specified if they
243 has just same syntax with above add|change|setglobal statement.
247 For each configuration file example shown below, we suppose
248 every IPv6 subnet has its own prefix beginning with
249 fec0:0:0::/48 and with its own subnet number.
251 subnet number is 7th and 8th octet value of the prefix)
253 If you want to assign prefixes beginning with fec0:1:1::/48
254 to each subnet, then following configuration will be enough,
255 if each of your routers supports IPv6 multicast forwarding.
256 The subnet number of the existing fec0:0:0::/48 prefix and the
257 newly assigned fec0:1:1::/48 prefix will be same.
259 .Bd -literal -offset indent
262 add match-prefix fec0:0:0:: /48 use-prefix fec0:1:1:: /48 keeplen 16;
266 If your routers don't support IPv6 multicast forwarding,
267 you'll need to specify each destination at
271 .Bd -literal -offset indent
272 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;
274 add match-prefix fec0:0:0:: /48 use-prefix fec0:1:1:: /48 keeplen 16;
278 If you are going to do renumbering, then following procedure will be natural.
279 .Bl -enum -offset indent
283 Set old prefix lifetimes to some appropriate transition
285 In the followng example we use 1 week for valid
286 lifetime, and 0 for preferred lifetime.
287 Also, enable old prefix lifetime expiration.
288 (By default, it is static and does not expire)
290 After the transition period, old prefixes should become
291 invalid, and may have been deleted.
292 To make sure that they are deleted, send new router
293 renumbering message, which specifies old prefixes as match
294 prefix, and no use prefix.
298 The following configuration file will do 1 and 2.
300 .Bd -literal -offset indent
304 add match-prefix fec0:0:0:: /48 use-prefix fec0:2:2:: /48 keeplen 16;
308 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;
313 And the following configuration file will do 3. (should be
314 used for the router renumbering message to be sent 1 week
317 .Bd -literal -offset indent
320 change match-prefix fec0:1:1:: /48;
324 In the above example, only
328 commands are used, and there is no example for
332 command is almost same with
334 command except that it deletes all pre-defined IPv6 global address.
342 configuration file was first appeared in KAME IPv6 protocol stack kit.
