H3C S6812 Series Command Reference Manual page 815

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

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
