remarks:        Route server operation could be modified with following large BGP communities:
remarks:        
remarks:        31230:0:peer-as - do not announce prefix to peer-as
remarks:        31230:1:peer-as - announce prefix to peer-as
remarks:        31230:100:peer-as - do not prepend when announcing to peer-as
remarks:        31230:101:peer-as - apply 1 prepend when announcing to peer-as
remarks:        31230:102:peer-as - apply 2 prepends when announcing to peer-as
remarks:        31230:103:peer-as - apply 3 prepends when announcing to peer-as
remarks:        
remarks:        When you set peer-as to 0, action will be performed for all SIX peers. This could be overriden
remarks:        by setting additional BGP community for specific peer-as.
remarks:        
remarks:        If your router doesn't support large BGP communities, for 16-bit AS you can also use standard
remarks:        community 0:peer-as which works the same way as community 31230:0:peer-as.
