         *********** BGP communities accepted from downstream **********
         ---------------------------------------------------------------

         1. Common, prepending to all peers (but not to customers):

         9002:6553X
         X < 5       prepend X times to all peers
         X = 5       advertise to customers but not to peers

         Note #1. If the downstream's route is not tagged with common
         community, then community 9002:65530 is applied on ReTN side
         (advertise everywhere without prepending)

        2. Regional, prepending to peers (not customers) in Regions:

         64666:6553X
         X < 5       prepend X times to all peers in Europe
         X = 5       advertise to customers but not to peers in EU

         64777:6553X
         X < 5       prepend X times to all peers in North America
         X = 5       advertise to customers but not to peers in NA

         64888:6553X
         X < 5       prepend X times to all peers in Asia-Pacific
         X = 5       advertise to customers but not to peers in APAC

         Note #2. If downstream tags the route with regional community,
         then common community 9002:6553X is ignored in proper Region

         3. Specific, prepending to peer ASN:

         ASN:6553X
         X < 5       prepend X times to peer ASN
         X = 5       do not advertise to peer ASN

         Note #3. Specific communities are applied for a limited subset
         of peers, listed below (see Appendix)

         Note #4. If downstream tags the route with specific community
         ASN:6553X, then common and regional communities are ignored
         while advertising to peer ASN (if present in Appendix)

         4. Blackhole:

         9002:666

         Note #5. Unaccepted bgp communities, including well-known ones,
         are ignored and stripped

         Appendix. Specific communities are applied for ASNs:
