Defining a Route Policy
This task explains how to define a route policy.
• If you want to modify an existing routing policy using the command-line interface (CLI), you must
redefine the policy by completing this task.
• Modifying the RPL scale configuration may take a long time.
• BGP may crash either due to large scale RPL configuration changes, or during consecutive RPL changes.
To avoid BGP crash, wait until there are no messages in the BGP In/Out queue before committing further
changes.
