IP Routing Features
Configuring IRDP
[ minadvertinterval < seconds > ]
This parameter specifies the minimum amount of time the
routing switch can wait between sending Router
Advertisements. Default: 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.
[preference < number >]
This 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.
Default: 0.
