Configuring IP Addressing
The only required task for IRDP routing on an interface is to enable IRDP processing on that interface.
When enabled, the default parameters apply. You can optionally change any of these parameters.
Beginning in privileged EXEC mode, follow these steps to enable and configure IRDP on an interface:
Command
Step 1
configure terminal
Step 2
interface interface-id
Step 3
ip irdp
Step 4
ip irdp multicast
Step 5
ip irdp holdtime seconds
Step 6
ip irdp maxadvertinterval seconds
Step 7
ip irdp minadvertinterval seconds
Step 8
ip irdp preference number
Step 9
ip irdp address address [number]
Step 10
end
Step 11
show ip irdp
Step 12
copy running-config startup-config
If you change the maxadvertinterval value, the holdtime and minadvertinterval values also change,
so it is important to first change the maxadvertinterval value, before manually changing either the
holdtime or minadvertinterval values.
Use the no ip irdp interface configuration command to disable IRDP routing.

Purpose
Enter global configuration mode.
Enter interface configuration mode, and specify the Layer 3 interface to
configure.
Enable IRDP processing on the interface.
(Optional) Send IRDP advertisements to the multicast address
(224.0.0.1) instead of IP broadcasts.
This command allows for compatibility with Sun Microsystems
Note
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) Set 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) Set the IRDP maximum interval between advertisements. The
default is 600 seconds.
(Optional) Set 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) Set a device IRDP preference level. The allowed range is –2
31
to 2
. The default is 0. A higher value increases the router preference
level.
(Optional) Specify an IRDP address and preference to proxy-advertise.
Return to privileged EXEC mode.
Verify settings by displaying IRDP values.
(Optional) Save your entries in the configuration file.
