Release Information
Junos OS 版本 9.2 中引入的语句。
在 EX 系列交换机 Junos OS 版本9.2 中引入的语句。
说明
将限制配置为可在 BGP 对等体会话中接受的前缀数。超过该限制时，将发送系统日志消息。
此语句提供记录消息、重置 BGP 会话的功能，或者在从对等方收到并被策略接受的前缀数量超过预设限制时执行此操作。此功能与prefix-limit功能相同，不同之处在于它根据接受的前缀（而非收到的前缀）运行。
选项
maximum number—设置最大前缀数时，超过该编号时将记录一条消息。
范围: 1到 4294967295 （232 – 1)
teardown <percentage>—必如果包含此teardown语句，当达到最大前缀数时，会话将被断开。如果指定百分比，则当前缀数量超过此百分比时，将记录消息。会话被切断后，将在短时间内重新建立，除非您包括此idle-timeout语句。然后可将会话保持在指定的一段时间，或者永远持续。如果指定forever，将仅在发出clear bgp neighbor命令后重新建立会话。
如果未teardown配置此语句，则当前缀数量超过为maximum选项配置的值时，将记录一条消息。
范围: 1到 100
idle-timeout (forever | timeout-in-minutes)—必如果包括此idle-timeout语句，则会话将在指定的时间段中断开，或永远失效。如果指定时段，将允许会话在此超时时间之后重新建立。如果指定forever，只有使用clear bgp neighbor命令干预之后，才会重新建立会话。
范围: 1到 2400
