IRDP commands
ip irdp
Use ip irdp to enable IRDP on an interface.
Use undo ip irdp to disable IRDP on an interface.
Syntax
ip irdp
undo ip irdp
Default
IRDP is disabled on an interface.
Views
Interface view
Predefined user roles
network-admin
Usage guidelines
This command validates the IRDP settings on an interface. After the IRDP is enabled on an interface, the device can send RA messages out of the interface.
Examples
# Enable IRDP on VLAN-interface 100.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] ip irdp
ip irdp address
Use ip irdp address to specify an IP address for an interface to proxy-advertise.
Use undo ip irdp address to remove the specified proxy-advertised IP address.
Syntax
ip irdp address ip-address preference-value
undo ip irdp address [ ip-address ]
Default
No proxy-advertised IP address is specified.

Parameters
ip-address: Specifies an IP address in dotted decimal notation.
preference-value: Specifies the preference for the IP address, in the range of –2147483648 to 2147483647. A larger preference value represents a higher preference.
Usage guidelines
You can specify a maximum of four IP addresses for an interface to proxy-advertise. An RA sent on the interface includes the interface IP addresses and the proxy-advertised IP addresses.
If you do not specify an IP address for the undo command, this command removes all proxy-advertised IP addresses from the interface.
Examples
# Specify the IP address 192.168.0.8 and its preference 1600 for VLAN-interface 100 to proxy-advertise.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] ip irdp address 192.168.0.8 1600

ip irdp
ip irdp interval
Use ip irdp interval to set the maximum and minimum intervals for advertising RAs on an interface.
Use undo ip irdp interval to restore the default.
Syntax
ip irdp interval max-interval [ min-interval ]
undo ip irdp interval
Default
The maximum interval is 600 seconds, and the minimum interval is 3/4 of the maximum interval.

Parameters
max-interval: Specifies the maximum interval in seconds, in the range of 4 to 1800.
min-interval: Specifies the minimum interval in seconds, in the range of 3 to max-interval.
Usage guidelines
The device broadcasts or multicasts an RA randomly between the maximum and minimum intervals.
Make sure the maximum interval is not longer than the lifetime of advertised IP addresses. Otherwise, the lifetime is automatically adjusted to a value three times the maximum interval.
Examples
# On VLAN-interface 100, set the maximum interval to 500 seconds and the minimum interval to 300 seconds.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] ip irdp interval 500 300
ip irdp
ip irdp lifetime
ip irdp lifetime
Use ip irdp lifetime to set the lifetime of IP addresses advertised on an interface.
Use undo ip irdp lifetime to restore the default.
Syntax
ip irdp lifetime lifetime-value
undo ip irdp lifetime
Default
The lifetime is 1800 seconds.

Parameters
lifetime-value: Specifies the lifetime in seconds, in the range of 4 to 9000.
Usage guidelines
The lifetime applies to the following IP addresses:
· IP addresses of the interface.
· IP addresses for the interface to proxy-advertise.
The lifetime cannot be shorter than the maximum advertising interval on an interface.
Examples
# Set the lifetime of IP addresses advertised on VLAN-interface 100 to 2000 seconds.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] ip irdp lifetime 2000

ip irdp multicast
Use ip irdp multicast to specify the multicast address 224.0.0.1 as the destination IP address for RAs sent on an interface.
Use undo ip irdp multicast to restore the default.
Syntax
ip irdp multicast
undo ip irdp multicast
Default
RAs use the broadcast address 255.255.255.255 as the destination IP address.

ip irdp preference
Use ip irdp preference to specify the preference of advertised primary and secondary IP addresses on an interface.
Use undo ip irdp preference to restore the default.
Syntax
ip irdp preference preference-value
undo ip irdp preference
Default
The preference of advertised IP addresses is 0.

Parameters
preference-value: Specifies the preference in the range of –2147483648 to 2147483647.
Usage guidelines
A larger preference value represents a higher preference. To request that neighboring hosts do not use any advertised IP address as the default gateway, set the value to the minimum value.
Examples
# Specify preference 1 for IP addresses advertised on VLAN-interface 100.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] ip irdp preference 1
