The router sends router advertisements on each interface configured to transmit messages. The advertisements include route information and indicate to network hosts that the router is operational. The router sends these messages periodically, with a time range defined by minimum and maximum values.
To modify the router advertisement interval, 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.
By default, the maximum advertisement interval is 600 seconds and the minimum advertisement interval is one-third the maximum interval, or 200 seconds.
