Configuring Graceful Restart for Multicast Snooping
When graceful restart is enabled for multicast snooping, no data traffic is lost during a process restart or a graceful Routing Engine switchover (GRES). Graceful restart can be configured for multicast snooping either at the global level or at the level of individual routing instances.
At the global level, graceful restart is enabled by default
for multicast snooping. To change this default setting, you can configure
the disable statement at the [edit multicast-snooping-options
graceful-restart] hierarchy level:
multicast-snooping-options { graceful-restart disable; }
To configure graceful restart for multicast snooping on a global level:
To configure graceful restart for multicast snooping for an individual routing instance level:
Configure the duration for graceful restart.
[edit routing-instances ri1 multicast-snooping-options graceful-restart] user@host# set restart-duration 200
The range for
restart-durationis from 0 through 300 seconds. The default value is 180 seconds. After this period, the Routing Engine resumes normal multicast operation.Note:You can also set the
graceful-restartstatement for an individual routing instance level at the[edit logical-systems logical-system-name routing-instances routing-instance-name multicast-snooping-options]hierarchy level.Verify your configuration by using the
show routing-instances routing-instance-name multicast-snooping-optionscommand.[edit] user@host# show routing-instances ri1 multicast-snooping-options
graceful-restart { restart-duration 200; }Commit the configuration.
