For specifying the BGP community attribute only, you also can specify community-ids as one of the following well-known community names defined in RFC 1997: no-advertise—Routes containing this community name are not advertised to other BGP peers. no-export—Routes containing this community name are not advertised outside a BGP confederation boundary. no-export-subconfed—Routes containing this community are advertised to IBGP peers with the same AS number, but not to members of other confederations. llgr-stale—Adds a community to a long-lived stale route when it is readvertised. no-llgr—Marks routes which a BGP speaker does not want to be retained by LLGR. The Notification message feature does not have any associated configuration parameters. https://www.juniper.net/documentation/us/en/software/junos/bgp/topics/ref/statement/community-edit-routing-options.html
