Release Information

Statement introduced in Junos OS Release 9.2.

Statement introduced in Junos OS Release 9.2 for EX Series switches.

Description

Configure a limit to the number of prefixes that can be accepted in a BGP peer session. When that limit is exceeded, a system log message is sent.

This statement provides the ability to log a message, reset the BGP session, or do both when the number of prefixes received from the peer and accepted by policy exceeds a preset limit. This functionality is identical to the prefix-limit functionality except that it operates against accepted prefixes rather than received prefixes.

Options

maximum numberWhen you set the maximum number of prefixes, a message is logged when that number is exceeded.

Range: 1 through 4,294,967,295 (232 – 1)

teardown <percentage>(Optional) If you include the teardown statement, the session is torn down when the maximum number of prefixes is reached. If you specify a percentage, messages are logged when the number of prefixes exceeds that percentage. After the session is torn down, it is reestablished in a short time unless you include the idle-timeout statement. Then the session can be kept down for a specified amount of time, or forever. If you specify forever, the session is reestablished only after you issue a clear bgp neighbor command.

If the teardown statement is not configured, a message is logged when the number of prefixes exceeds the value configured for the maximum option.

Range: 1 through 100

idle-timeout (forever | timeout-in-minutes)(Optional) If you include the idle-timeout statement, the session is torn down for a specified amount of time, or forever. If you specify a period of time, the session is allowed to reestablish after this timeout period. If you specify forever, the session is reestablished only after you intervene with a clear bgp neighbor command.

Range: 1 through 2400
