Global range setting for initial router advertisement intervals

You can configure override options to set a global range from which the router randomly selects an interval for each interface for only the initial three router advertisements that the router sends when the router becomes available on that interface. This enables you to set a range that results in a very short interval for these advertisements without affecting subsequent advertisements set by the router. You can configure an interval range only per interface and the range settings apply to all router advertisements that the router sends.
