IS-IS路由器配置了graceful-restart interval,其邻居会将interval-value设置为邻居保持时间,缺省情况下,GR T3定时器为300秒

配置IS-IS GR后,邻居的holdtime值如果小于60秒,则修改为60秒,否则保持原holdtime值

graceful-restart no-impact-holdtime命令用来配置IS-IS邻居的Holdtime不受GR影响(v200r002及以上版本支持)

解决方案

 配置graceful-restart no-impact-holdtime使IS-IS在使能GR后邻居的holdtime保持不变

[Quidway] isis 100
[Quidway-isis-100] graceful-restart
[Quidway-isis-100] graceful-restart no-impact-holdtime
