Usage Guidelines

Usage Scenario

To enable a device to advertise the Large-Community attribute to its BGP peer or peer group, run the peer advertise-large-community command. If the Large-Community attribute is advertised to a peer group, all the peer members in the group inherit this configuration. This simplifies the application of route-policies and facilitates route maintenance and management.

Prerequisites

Specific Large-Community values have been defined in a route-policy.
