.Nd configuration file for router renumbering daemon
|
|
.\"
|
|
.Sh DESCRIPTION
|
|
The rrenumd config file describes how the router renumbering packet
|
|
must be constructed and to which destinations it should be sent.
|
|
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 EXAMPLES
|
|
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.

|
|
.Ed
|
|
.\"
|
|
|
|
If your routers don't support IPv6 multicast forwarding,
|
|
you'll need to specify each destination at
|
|
.Cm dest
|
|
command.

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.
