62 IP Routing Features
Specifies the packet type the routing switch uses to send the
Router Advertisement:
The routing switch sends Router Advertisements
broadcast
as IP broadcasts.
The routing switch sends Router Advertisements
multicast
as multicast packets addressed to IP multicast
group 224.0.0.1. This is the default.
Specifies how long a host that receives a Router Advertisement
from the routing switch should consider the advertisement to be
valid.
When a host receives a new Router Advertisement message from
the routing switch, the host resets the hold time for the routing
switch to the hold time specified in the new advertisement. If the
hold time of an advertisement expires, the host discards the
advertisement, concluding that the router interface that sent the
advertisement is no longer available. The value must be greater
than the value of the maxadvertinterval parameter and cannot
be greater than 9000.
The default is three times the value of the maxadvertinterval
parameter.
Specifies the maximum amount of time the routing switch waits
between sending Router Advertisements. You can specify a value
from 1 to the current value of the holdtime parameter.
The default is 600 seconds.
Specifies the minimum amount of time the routing switch can
wait between sending Router Advertisements. The default is
three-fourths (0.75) the value of the maxadvertinterval parameter.
If you change the maxadvertinterval parameter, the software
automatically adjusts the minadvertinterval parameter to be
three-fourths the new value of the maxadvertinterval parameter.
If you want to override the automatically configured value, you
can specify an interval from 1 to the current value of the
maxadvertinterval parameter.
Specifies the IRDP preference level of this routing switch. If a host
receives Router Advertisements from multiple routers, the host
selects the router interface that sent the message with the highest
preference as the host's default gateway.
The valid range is -4294967296 to 4294967295.
The default is 0.
