.Op Fl P Ar policy

.Ar interface ...
|
||||
.Sh DESCRIPTION
|
||||
.Nm Rtadvd
|
||||
.Nm
|
||||
advertises router advertisement packet to the specified
|
||||
.Ar interfaces .
|
||||
.Pp
|
||||
The program will daemonize itself on invocation.
|
||||
Then, it will voluntarily send router advertisement packet periodically.
|
||||
If a router solicitation packet from host has reached the program,
|
||||
the program will respond by router advertisement packet.
|
||||
It will then periodically send router advertisement packets, as well
|
||||
as in response to router solicitation messages sent by end hosts.
|
||||
.Pp
|
||||
For each interface, which is called advertising interface,
|
||||
content of router advertisement can be described in
|
||||
Router advertisements can be configured on a per-interface basis, as
|
||||
described in
|
||||
.Xr rtadvd.conf 5 .
|
||||
.Pp
|
||||
If there is no description for the interface in the configuration file
|
||||
or if the configuration file does not exist,
|
||||
In the event of no configuration file entry for an interface,
|
||||
or if the configuration file does not exist altogether,
|
||||
.Nm
|
||||
sets all the parameters to their default values.
|
||||
In particular,
|
||||
.Nm
|
||||
gets all the interface routes from the routing table and advertises
|
||||
reads all the interface routes from the routing table and advertises
|
||||
them as on-link prefixes.
|
||||
.Pp
|
||||
.Nm Rtadvd
|
||||
watches the routing table.
|
||||
.Nm
|
||||
also watches the routing table.
|
||||
By default, if an interface direct route is
|
||||
added/deleted on an advertising interface,
|
||||
added/deleted on an advertising interface and no static prefixes are
|
||||
specified by the configuration file,
|
||||
.Nm
|
||||
adds/deletes the corresponding prefix to/from its advertising list,
|
||||
respectively.
|
||||
If you do not want to enable this feature, you should specify the
|
||||
The
|
||||
.Ic Fl s
|
||||
command line option when advocation.
|
||||
may be used to disable this behavior.
