The capability to explicitly enable or disable the sending of the BGP community attribute to BGP neighbors, other than through the use of policy statements, is supported.
This feature allows an administrator to enable or disable the sending of BGP communities to an associated peer. This feature overrides communities that are already associated with a specific route or that may have been added via an export route policy. That is, even if the export policies leave BGP communities attached to a specific route, when the disable-communities feature is enabled, no BGP communities are advertised to the associated BGP peers.
