Configuring the Frequency of ICMP Router Advertisements
The router discovery server sends router advertisement messages, which include route information and indicate to network hosts that the router is still operational. The server sends these messages periodically, with a time range defined by minimum and maximum values. By default, the server sends router advertisements every 400 to 600 seconds. To modify these times, include the min-advertisement-interval and max-advertisement-interval statements:
min-advertisement-interval seconds;max-advertisement-interval seconds;
For a list of hierarchy levels at which you can include these statements, see the statement summary sections for these statements.
