Usage Guidelines

In a hot standby scenario, service modules can be associated with a route monitoring group to trigger link switchovers. When the status of the route monitoring group goes Up, the RM module instructs the associated service modules to perform link switchbacks. In addition, the RM module re-delivers routes to the forwarding table and establishes forwarding entries for the routes, which takes some time. Packet loss may occur if the RM module instructs the associated service modules to perform link switchovers immediately. To resolve this problem, run the trigger-up-delay command to configure a delay after which the RM module instructs the associated service modules to perform link switchbacks.

Example

# Set the delay to 10s after which the RM module instructs the associated service modules to perform link switchbacks.
