Usage Scenario
The Large-Community attribute is a private attribute of BGP and can be flexibly applied to route-policies. To modify or set values of the Large-Community attribute in BGP routes, run the apply large-community-list command.
Configuration Impact
If the apply large-community-list command is run in a route-policy, the values of the Large-Community attribute in the BGP routes filtered by the route-policy will be changed to the value in the route-policy.
Precautions
If the apply large-community-list command is run more than once, the latest configuration overrides the previous one.
