Accepted Prefix Limit

You can limit the number of prefixes that can be accepted on a BGP peer session. When that specified limit is exceeded, a system log message is sent. Optionally, you can also force persistent or temporal teardown of the BGP session, if the limit to the number of specified prefixes is exceeded. You can specify the accepted prefix limit as a value from 1 through 4,294,967,295. When session teardown is enabled, you can specify a threshold (percentage value from 1 through 100) to have a system log message sent when the number of accepted prefixes exceeds that percentage of the maximum limit. By default, a BGP session that is reset is reestablished within a short time. Alternatively, you can specify some idle timeout value to prevent the BGP session from being reestablished for a specified period of time, or specify the forever option to prevent the BGP session from being reestablished until the BGP session is manually cleared. This functionality is identical to the received prefix limit functionality except that it operates against accepted prefixes rather than received prefixes.
