min-interval-value: Minimum interval for advertising RA messages in seconds, in the range of 3 to 1,350.
Description
Use ipv6 nd ra interval to set the maximum and minimum intervals for advertising RA messages. The
firewall advertises RA messages at intervals of a random value between the maximum interval and the
minimum interval.
Use undo ipv6 nd ra interval to restore the default.
By default, the maximum interval between RA messages is 600 seconds, and the minimum interval is
200 seconds.
Note the following:
• The minimum interval should be three-fourths of the maximum interval or less.
• The maximum interval for sending RA messages should be less than or equal to the router lifetime
in RA messages.
Examples
# Set the maximum interval for advertising RA messages to 1,000 seconds and the minimum interval to
700 seconds.
