ipv6 nd ra-interval

Configures the interval at which an interface sends router advertisement messages.
Syntax
ipv6 nd ra-interval [ range min-interval max-interval | interval ]
no ipv6 nd ra-interval [ range min-interval max-interval | interval ]
Command Default

By default, an interface sends a router advertisement message every 200 seconds.

Parameters
range min-interval max-interval
Configures an interval range. The min-range-value specifies the minimum number of seconds allowed between sending unsolicited multicast router advertisements from the interface. The default is 0.33 times the max-range-value if the max-range-value is greater than or equal to 9 seconds. Otherwise, the default is the value specified by the max-range-value. The min-range-value can be a number between -3 - (.75 x max range value ). The max-range-value parameter specifies the maximum number of seconds allowed between sending unsolicited multicast router advertisements from the interface. This number can be between 4 - 1800 seconds and must be greater than the min-range-value x 1.33. The default is 600 seconds.
interval
Configures the interval. Valid values are 3 to1800 seconds. The default is 200 seconds. The actual RA interval will be from .5 to 1.5 times the configured or default value.
Modes

Interface configuration mode

Usage Guidelines

RUCKUS recommends that the interval between router advertisement transmission be less than or equal to the router lifetime value if the router is advertised as a default router.

The no form of the command resets the interface at which an interface sends a router advertisement message to 200 seconds.

Examples

The following example configures the interval at which an interface sends a router advertisement message as 300 seconds.

device(config)# interface ethernet 1/3/1
device(config-if-e1000-1/3/1)# ipv6 nd ra-interval 300

The following example configures the interval at which an interface sends a router advertisement message to a range.

device(config)# interface ethernet 1/3/1
device(config-if-e1000-1/3/1)# ipv6 nd ra-interval range 33 55
