Configuring the range for intervals between RA transmissions on a VLAN

The interval between RA transmissions on a VLAN is a random value that changes every time an RA is sent. The interval is calculated to be a value between the current max-interval and min-interval settings described below.

Syntax:

ipv6 nd ra max-interval <4–1800>

no ipv6 nd ra max-interval <4–1800>

ipv6 nd ra min-interval <3–1350>

no ipv6 nd ra min-interval <3–1350>

VLAN context commands for changing the maximum and minimum intervals between transmissions of IPv6 RAs on the VLAN. These values have one setting per VLAN and do not apply to RAs sent in response to a router solicitation received from another device.

max-interval : Must be equal to or less than the configured lifetime setting. Attempting to set max-interval to a value greater than the configured lifetime setting results in an error message.

The no form of the max-interval command returns the setting to its default, provided the default value is less than or equal to 75% of the new maximum interval you are setting.

Attempting to set max-interval to a value that is not sufficiently larger than the current min-interval also results in an error message.

Default: 600 seconds; Range: 4–1800 seconds

min-interval : Must be less than or equal to 75% of max-interval. Attempting to set min-interval to a higher value results in an error message.

The no form of the min-interval command returns the setting to its default, provided the default value is less than or equal to 75% of the current max-interval setting.

Default: 200 seconds; Range: 3–1350 seconds
