debug on|off; | |
Enables configuration file parser debugging. If on is specified, then debugging is enabled, If off is specified, then debugging is disabled. It is disabled by default. | |
dest dest-list [retrycmd]; | |
Specifies destinations to which router renumbering messages should be sent. dest-list can be any combination of single or multiple numerical IPv6 addrs, or Full Qualified Domain Names. retrycmd has following syntax. | |
retry retry-num | |
retry-num specifies how many router renumbering messages are sent repeatedly. | |
[ add|change|setglobal] | |
match-prefix match-prefix-val
[/match-prefix-len]
[ maxlen maxlen-val]
[ minlen minlen-val]
[ use-prefix use-prefix-val]
[/use-prefix-len]
[ keeplen keeplen-val]
[use-prefix-values];
Specifies contents of sending router renumbering message with seqnum 0. If add|change|setglobal is not specified, then add is assumed. use-prefix-values has following syntax. { [ vltime vltime-val] [ pltime pltime-val] [ raf_onlink on|off] [ raf_auto on|off] [ rrf_decrprefd on|off] [ rrf_decrvalid on|off] } Each value has following meaning.
| |
match-prefix match-prefix-val [/match-prefix-len] | |
Specify match-prefix-val that is used for matching with preassigned prefixes to which add|change|setglobal command should be applied. /match-prefix-len Specify the starting part of match-prefix-val to be used for matching with preassigned prefixes, as decimal bit number. | |
maxlen maxlen-val | |
Specify the maximum length of prefixes which is allowed to be matched to match-prefix-val, as decimal bit number. | |
minlen minlen-val | |
Specify the minimum length of prefixes which is allowed to be matched to match-prefix-val, as decimal bit number. | |
use-prefix use-prefix-val [/usr-prefix-len] | |
Specify use-prefix-val that is used for prefixes to be added on add|change|setglobal command. /use-prefix-len Specify the starting part of use-prefix-val copied to the starting part of prefixes to be added on add|change|setglobal command, as decimal bit number. | |
keeplen keeplen-val | |
Specify the medium part of use-prefix-val just next to the starting part specified by use-prefix-len, as decimal bit number. Contiguous bits part in the same bit position of an existent prefix matched with match-prefix-val is copied to the same bit position of prefixes to be added. | |
vltime vmtime-val | |
Assign an time as prefix valid life time for a prefix to be added. Valid value for 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. | |
pltime pltime-val | |
Assign an time as prefix preferred life time for a prefix to be added. Valid value for time is same as for vltime-val. | |
raf_onlink on|off | |
Let the prefix to be added to have on-link or off-link nature for the assigned interface. If on is specified, the prefix have on-link nature (e.g.amp; the prefix belong to the link). If off is specified, the prefix have off-link nature (e.g.amp; the prefix does not belong to the link). | |
raf_auto on|off | |
Enable or disable the autonomous address auto configuration for the prefix to be added. If on is specified, autonomous address auto configuration is enabled. If off is specified, it is disabled. | |
rrf_decrprefd on|off | |
Enable or disable the decrementation of the pltime. If on is specified, decrementation of the pltime is enabled. If off is specified, decrementation of the pltime is disabled. | |
rrf_decrvalid on|off | |
Enable or disable the decrementation of the vltime. If on is specified, decrementation of the vltime is enabled. If off is specified, decrementation of the vltime is disabled. | |
seqnum seqnum-val { rrenum-cmd }; | |
Specifies contents of sending router renumbering message with some specific seqnum. Multiple of this statement can be specified if they have different seqnum-val each other. rrenum-cmd has just same syntax with above add|change|setglobal statement. | |
If you want to assign prefixes beginning with 3ffe:501:ffff::/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 3ffe:501:ffff::/48 prefix will be same.
dest ff05::2;add match-prefix fec0:0:0:: /48 use-prefix 3ffe:501:ffff:: /48 keeplen 16;
If your routers do not support IPv6 multicast forwarding, you will need to specify each destination at dest command.
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 3ffe:501:ffff:: /48 keeplen 16;
If you are going to do renumbering, then following procedure will be natural.
The following configuration file will do 1 and 2.
dest ff05::2;seqnum 0 { add match-prefix fec0:0:0:: /48 use-prefix 3ffe:501:fffe:: /48 keeplen 16; };
seqnum 1 { change match-prefix 3ffe:501:ffff:: /48 use-prefix 3ffe:501:ffff:: /48 keeplen 16 vltime d7 pltime 0 rrf_decrvalid on rrf_decrprefd on; };
And the following configuration file will do 3 (should be used for the router renumbering message to be sent 1 week afterward).
dest ff05::2;change match-prefix 3ffe:501:ffff:: /48;
In the above example, only add and change commands are used, and there is no example for setglobal command. setglobal command is almost same with change command except that it deletes all pre-defined IPv6 global address.
