Gateway Routing Daemon (GATED) Configuration Reference
A.15 The Router Discovery Protocol
The Router Discovery Server syntax is as follows:
routerdiscovery server yes | no | on | off [ {
traceoptions trace_options ;
interface interface_list
[ minadvinterval time ]
[ maxadvinterval time ]
[ lifetime time ]
;
address interface_list
[ advertise ] | [ ignore ]
[ broadcast ] | [ multicast ]
[ ineligible ] | [ preference preference ]
;
}];
The Router Discovery Server syntax includes the following:
• traceoptions specifies the Router Discovery tracing options (see
Section A.15.3).
• interface specifies the parameters that apply to physical interfaces. Note a
slight difference in convention from the rest of GATED, interface specifies
just physical interfaces (such as LE0, EF0 and EN1), while address specifies
protocol (in this case IP) addresses.
The interface parameters are:
maxadvinterval specifies the maximum time allowed between sending
broadcast or multicast Router Advertisements from the interface. Must
be no less than 4 and no more than 30:00 (30 minutes or 1800 seconds).
The default is 10:00 (10 minutes or 600 seconds).
minadvinterval specifies the minimum time allowed between sending
unsolicited broadcast or multicast Router Advertisements from the
interface. Must be no less than 3 seconds and no greater than
maxadvinterval. The default is 0.75 * maxadvinterval .
lifetime specifies the life time of addresses in a Router Advertisement.
Must be no less than maxadvinterval and no greater than 2:30:00
(two hours, thirty minutes or 9000 seconds). The default is 3 *
maxadvinterval .
•
address specifies the parameters that apply to the specified set of addresses
on this physical interfaces. Note a slight difference in convention from the
rest of GATED, interface specifies just physical interfaces (such as LE0, EF0
and EN1), while address specifies protocol (in this case IP) addresses.
The address parameters are:
advertise , which Specifies that the specified addresses should be included
in Router Advertisements. This is the default.
ignore , which specifies that the specified addresses should not be included
in Router Advertisements.
broadcast , which specifies that the given addresses should be included in
a broadcast Router Advertisement because this system does not support
IP multicasting, or some hosts on attached network do not support IP
multicasting. It is possible to mix addresses on a physical interface such
that some are included in a broadcast Router Advertisement and some are
included in a multicast Router Advertisement. broadcast is the default if
the router does not support IP multicasting.
