IP Routing Features
Configuring IRDP
Syntax: [no] ip irdp
Enables or disables (the default) ip irdp on the specified
VLAN.
[broadcast | multicast]
This parameter specifies the packet type the routing
switch uses to send the Router Advertisement:
broadcast - The routing switch sends Router
Advertisements as IP broadcasts.
multicast - The routing switch sends Router
Advertisements as multicast packets addressed to IP
multicast group 224.0.0.1. This is the default.
[ holdtime < seconds >]
This parameter 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.
[maxadvertinterval < seconds >]
This 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. Default: 600 (seconds).
