Configuring IP Unicast Routing
Purpose
Enters interface configuration mode, and specifies the
Layer 3 interface to configure.
Enables IRDP processing on the interface.
(Optional) Sends IRDP advertisements to the multicast
address (224.0.0.1) instead of IP broadcasts.
This command allows for compatibility with
Note
Sun Microsystems Solaris, which requires
IRDP packets to be sent out as multicasts.
Many implementations cannot receive these
multicasts; ensure end-host ability before using
this command.
(Optional) Sets the IRDP period for which
advertisements are valid. The default is three times the
maxadvertinterval value. It must be greater than
maxadvertinterval and cannot be greater than 9000
seconds. If you change the maxadvertinterval value,
this value also changes.
(Optional) Sets the IRDP maximum interval between
advertisements. The default is 600 seconds.
(Optional) Sets the IRDP minimum interval between
advertisements. The default is 0.75 times the
maxadvertinterval. If you change the
maxadvertinterval, this value changes to the new
default (0.75 of maxadvertinterval).
(Optional) Sets a device IRDP preference level. The
allowed range is –231 to 231. The default is 0. A higher
value increases the router preference level.
